/**
 * @class Ext.DomHelper
 * <p>The DomHelper class provides a layer of abstraction from DOM and transparently supports creating
 * elements via DOM or using HTML fragments. It also has the ability to create HTML fragment templates
 * from your DOM building code.</p>
 *
 * <p><b><u>DomHelper element specification object</u></b></p>
 * <p>A specification object is used when creating elements. Attributes of this object
 * are assumed to be element attributes, except for 4 special attributes:
 * <div class="mdetail-params"><ul>
 * <li><b><tt>tag</tt></b> : <div class="sub-desc">The tag name of the element</div></li>
 * <li><b><tt>children</tt></b> : or <tt>cn</tt><div class="sub-desc">An array of the
 * same kind of element definition objects to be created and appended. These can be nested
 * as deep as you want.</div></li>
 * <li><b><tt>cls</tt></b> : <div class="sub-desc">The class attribute of the element.
 * This will end up being either the "class" attribute on a HTML fragment or className
 * for a DOM node, depending on whether DomHelper is using fragments or DOM.</div></li>
 * <li><b><tt>html</tt></b> : <div class="sub-desc">The innerHTML for the element</div></li>
 * </ul></div></p>
 *
 * <p><b><u>Insertion methods</u></b></p>
 * <p>Commonly used insertion methods:
 * <div class="mdetail-params"><ul>
 * <li><b><tt>{@link #append}</tt></b> : <div class="sub-desc"></div></li>
 * <li><b><tt>{@link #insertBefore}</tt></b> : <div class="sub-desc"></div></li>
 * <li><b><tt>{@link #insertAfter}</tt></b> : <div class="sub-desc"></div></li>
 * <li><b><tt>{@link #overwrite}</tt></b> : <div class="sub-desc"></div></li>
 * <li><b><tt>{@link #createTemplate}</tt></b> : <div class="sub-desc"></div></li>
 * <li><b><tt>{@link #insertHtml}</tt></b> : <div class="sub-desc"></div></li>
 * </ul></div></p>
 *
 * <p><b><u>Example</u></b></p>
 * <p>This is an example, where an unordered list with 3 children items is appended to an existing
 * element with id <tt>'my-div'</tt>:<br>
 <pre><code>
var dh = Ext.DomHelper; // create shorthand alias
// specification object
var spec = {
    id: 'my-ul',
    tag: 'ul',
    cls: 'my-list',
    // append children after creating
    children: [     // may also specify 'cn' instead of 'children'
        {tag: 'li', id: 'item0', html: 'List Item 0'},
        {tag: 'li', id: 'item1', html: 'List Item 1'},
        {tag: 'li', id: 'item2', html: 'List Item 2'}
    ]
};
var list = dh.append(
    'my-div', // the context element 'my-div' can either be the id or the actual node
    spec      // the specification object
);
 </code></pre></p>
 * <p>Element creation specification parameters in this class may also be passed as an Array of
 * specification objects. This can be used to insert multiple sibling nodes into an existing
 * container very efficiently. For example, to add more list items to the example above:<pre><code>
dh.append('my-ul', [
    {tag: 'li', id: 'item3', html: 'List Item 3'},
    {tag: 'li', id: 'item4', html: 'List Item 4'}
]);
 * </code></pre></p>
 *
 * <p><b><u>Templating</u></b></p>
 * <p>The real power is in the built-in templating. Instead of creating or appending any elements,
 * <tt>{@link #createTemplate}</tt> returns a Template object which can be used over and over to
 * insert new elements. Revisiting the example above, we could utilize templating this time:
 * <pre><code>
// create the node
var list = dh.append('my-div', {tag: 'ul', cls: 'my-list'});
// get template
var tpl = dh.createTemplate({tag: 'li', id: 'item{0}', html: 'List Item {0}'});

for(var i = 0; i < 5, i++){
    tpl.append(list, [i]); // use template to append to the actual node
}
 * </code></pre></p>
 * <p>An example using a template:<pre><code>
var html = '<a id="{0}" href="{1}" class="nav">{2}</a>';

var tpl = new Ext.DomHelper.createTemplate(html);
tpl.append('blog-roll', ['link1', 'http://www.jackslocum.com/', "Jack&#39;s Site"]);
tpl.append('blog-roll', ['link2', 'http://www.dustindiaz.com/', "Dustin&#39;s Site"]);
 * </code></pre></p>
 *
 * <p>The same example using named parameters:<pre><code>
var html = '<a id="{id}" href="{url}" class="nav">{text}</a>';

var tpl = new Ext.DomHelper.createTemplate(html);
tpl.append('blog-roll', {
    id: 'link1',
    url: 'http://www.jackslocum.com/',
    text: "Jack&#39;s Site"
});
tpl.append('blog-roll', {
    id: 'link2',
    url: 'http://www.dustindiaz.com/',
    text: "Dustin&#39;s Site"
});
 * </code></pre></p>
 *
 * <p><b><u>Compiling Templates</u></b></p>
 * <p>Templates are applied using regular expressions. The performance is great, but if
 * you are adding a bunch of DOM elements using the same template, you can increase
 * performance even further by {@link Ext.Template#compile "compiling"} the template.
 * The way "{@link Ext.Template#compile compile()}" works is the template is parsed and
 * broken up at the different variable points and a dynamic function is created and eval'ed.
 * The generated function performs string concatenation of these parts and the passed
 * variables instead of using regular expressions.
 * <pre><code>
var html = '<a id="{id}" href="{url}" class="nav">{text}</a>';

var tpl = new Ext.DomHelper.createTemplate(html);
tpl.compile();

//... use template like normal
 * </code></pre></p>
 *
 * <p><b><u>Performance Boost</u></b></p>
 * <p>DomHelper will transparently create HTML fragments when it can. Using HTML fragments instead
 * of DOM can significantly boost performance.</p>
 * <p>Element creation specification parameters may also be strings. If {@link #useDom} is <tt>false</tt>,
 * then the string is used as innerHTML. If {@link #useDom} is <tt>true</tt>, a string specification
 * results in the creation of a text node. Usage:</p>
 * <pre><code>
Ext.DomHelper.useDom = true; // force it to use DOM; reduces performance
 * </code></pre>
 * @singleton

 * @class Ext.DomQuery
Provides high performance selector/xpath processing by compiling queries into reusable functions. New pseudo classes and matchers can be plugged. It works on HTML and XML documents (if a content node is passed in).
<p>
DomQuery supports most of the <a href="http://www.w3.org/TR/2005/WD-css3-selectors-20051215/#selectors">CSS3 selectors spec</a>, along with some custom selectors and basic XPath.</p>

<p>
All selectors, attribute filters and pseudos below can be combined infinitely in any order. For example "div.foo:nth-child(odd)[@foo=bar].bar:first" would be a perfectly valid selector. Node filters are processed in the order in which they appear, which allows you to optimize your queries for your document structure.
</p>
<h4>Element Selectors:</h4>
<ul class="list">
    <li> <b>*</b> any element</li>
    <li> <b>E</b> an element with the tag E</li>
    <li> <b>E F</b> All descendent elements of E that have the tag F</li>

 * For example:
 * <pre><code>

        // Call our superclass constructor to complete construction process.
        Employee.superclass.constructor.call(config)
    }
});
</code></pre>
 * This could then be used like this:<pre><code>
var newEmployee = new Employee({

        quit: function() {

 * @class Ext.Element
 * <p>Encapsulates a DOM element, adding simple DOM manipulation facilities, normalizing for browser differences.</p>
 * <p>All instances of this class inherit the methods of {@link Ext.Fx} making visual effects easily available to all DOM elements.</p>
 * <p>Note that the events documented in this class are not Ext events, they encapsulate browser events. To
 * access the underlying browser event, see {@link Ext.EventObject#browserEvent}. Some older
 * browsers may not support the full range of events. Which events are supported is beyond the control of ExtJs.</p>
 * Usage:<br>
<pre><code>
// by id
var el = Ext.get("my-div");

// by DOM element reference
var el = Ext.get(myDivElement);
</code></pre>
 * <b>Animations</b><br />
 * <p>When an element is manipulated, by default there is no animation.</p>
 * <pre><code>
var el = Ext.get("my-div");

// no animation
el.setWidth(100);
 * </code></pre>
 * <p>Many of the functions for manipulating an element have an optional "animate" parameter.  This
 * parameter can be specified as boolean (<tt>true</tt>) for default animation effects.</p>
 * <pre><code>
// default animation
el.setWidth(100, true);
 * </code></pre>
 * 
 * <p>To configure the effects, an object literal with animation options to use as the Element animation
 * configuration object can also be specified. Note that the supported Element animation configuration
 * options are a subset of the {@link Ext.Fx} animation options specific to Fx effects.  The supported
 * Element animation configuration options are:</p>
<pre>
Option    Default   Description
--------- --------  ---------------------------------------------
{@link Ext.Fx#duration duration}  .35       The duration of the animation in seconds
{@link Ext.Fx#easing easing}    easeOut   The easing method
{@link Ext.Fx#callback callback}  none      A function to execute when the anim completes
{@link Ext.Fx#scope scope}     this      The scope (this) of the callback function
</pre>
 * 
 * <pre><code>
// Element animation options object
var opt = {
    {@link Ext.Fx#duration duration}: 1,
    {@link Ext.Fx#easing easing}: 'elasticIn',
    {@link Ext.Fx#callback callback}: this.foo,
    {@link Ext.Fx#scope scope}: this
};
// animation with some options set
el.setWidth(100, opt);
 * </code></pre>
 * <p>The Element animation object being used for the animation will be set on the options
 * object as "anim", which allows you to stop or manipulate the animation. Here is an example:</p>
 * <pre><code>
// using the "anim" property to get the Anim object
if(opt.anim.isAnimated()){
    opt.anim.stop();
}
 * </code></pre>
 * <p>Also see the <tt>{@link #animate}</tt> method for another animation technique.</p>
 * <p><b> Composite (Collections of) Elements</b></p>
 * <p>For working with collections of Elements, see {@link Ext.CompositeElement}</p>
 * @constructor Create a new Element directly.
 * @param {String/HTMLElement} element
 * @param {Boolean} forceNew (optional) By default the constructor checks to see if there is already an instance of this element in the cache and if there is it returns the same instance. This will skip that check (useful for extending this class).

     * In the following examples, the shorthand form {@link #on} is used rather than the more verbose

     * types of listeners:<br>
     * <br>
     * A delayed, one-time listener that auto stops the event and adds a custom argument (forumId) to the
     * options object. The options object is available as the third parameter in the handler function.<div style="margin: 5px 20px 20px;">
     * Code:<pre><code>
el.on('click', this.onClick, this, {
    single: true,
    delay: 100,
    stopEvent : true,
    forumId: 4
});</code></pre></p>
     * <p>
     * <b>Attaching multiple handlers in 1 call</b><br>
     * The method also allows for a single argument to be passed which is a config object containing properties
     * which specify multiple handlers.</p>
     * <p>
     * Code:<pre><code>
el.on({
    'click' : {
        fn: this.onClick,
        scope: this,
        delay: 100
    },
    'mouseover' : {
        fn: this.onMouseOver,
        scope: this
    },
    'mouseout' : {
        fn: this.onMouseOut,
        scope: this
    }
});</code></pre>
     * <p>

     * Code:<pre><code></p>
el.on({
    'click' : this.onClick,
    'mouseover' : this.onMouseOver,
    'mouseout' : this.onMouseOut,
    scope: this
});
     * </code></pre></p>
     * <p><b>delegate</b></p>
     * <p>This is a configuration option that you can pass along when registering a handler for
     * an event to assist with event delegation. Event delegation is a technique that is used to
     * reduce memory consumption and prevent exposure to memory-leaks. By registering an event
     * for a container element as opposed to each element within a container. By setting this
     * configuration option to a simple selector, the target element will be filtered to look for
     * a descendant of the target.
     * For example:<pre><code>
// using this markup:
&lt;div id='elId'>
    &lt;p id='p1'>paragraph one&lt;/p>
    &lt;p id='p2' class='clickable'>paragraph two&lt;/p>
    &lt;p id='p3'>paragraph three&lt;/p>
&lt;/div>
// utilize event delegation to registering just one handler on the container element: 
el = Ext.get('elId');
el.on(
    'click',
    function(e,t) {
        // handle click
        console.info(t.id); // 'p2'
    },
    this,
    {
        // filter the target element to be a descendant with the class 'clickable'
        delegate: '.clickable'

     * Aligns this element with another element relative to the specified anchor points. If the other element is the
     * document it aligns it to the viewport.
     * The position parameter is optional, and can be specified in any one of the following formats:
     * <ul>
     *   <li><b>Blank</b>: Defaults to aligning the element's top-left corner to the target's bottom-left corner ("tl-bl").</li>
     *   <li><b>One anchor (deprecated)</b>: The passed anchor position is used as the target element's anchor point.
     *       The element being aligned will position its top-left corner (tl) to that point.  <i>This method has been
     *       deprecated in favor of the newer two anchor syntax below</i>.</li>
     *   <li><b>Two anchors</b>: If two values from the table below are passed separated by a dash, the first value is used as the
     *       element's anchor point, and the second value is used as the target's anchor point.</li>
     * </ul>
     * In addition to the anchor points, the position parameter also supports the "?" character.  If "?" is passed at the end of
     * the position string, the element will attempt to align as specified, but the position will be adjusted to constrain to
     * the viewport if necessary.  Note that the element being aligned might be swapped to align to a different position than
     * that specified in order to enforce the viewport constraints.
     * Following are all of the supported anchor positions:
<pre>
Value  Description
-----  -----------------------------
tl     The top left corner (default)
t      The center of the top edge
tr     The top right corner
l      The center of the left edge
c      In the center of the element
r      The center of the right edge
bl     The bottom left corner
b      The center of the bottom edge
br     The bottom right corner
</pre>
Example Usage:
<pre><code>
// align el to other-el using the default positioning ("tl-bl", non-constrained)
el.alignTo("other-el");

// align the top left corner of el with the top right corner of other-el (constrained to viewport)
el.alignTo("other-el", "tr?");

// align the bottom right corner of el with the center left edge of other-el
el.alignTo("other-el", "br-l?");

// align the center of el with the bottom left corner of other-el and
// adjust the x position by -6 pixels (and the y position by 0)
el.alignTo("other-el", "c-bl", [-6, 0]);
</code></pre>
     * @param {Mixed} element The element to align to.
     * @param {String} position The position to align to.
     * @param {Array} offsets (optional) Offset the positioning by [x, y]
     * @param {Boolean/Object} animate (optional) true for the default animation or a standard Element animation config object

/**
 * @class Ext.Fx
 * <p>A class to provide basic animation and visual effects support.  <b>Note:</b> This class is automatically applied
 * to the {@link Ext.Element} interface when included, so all effects calls should be performed via {@link Ext.Element}.
 * Conversely, since the effects are not actually defined in {@link Ext.Element}, Ext.Fx <b>must</b> be
 * {@link Ext#enableFx included} in order for the Element effects to work.</p><br/>
 * 
 * <p><b><u>Method Chaining</u></b></p>
 * <p>It is important to note that although the Fx methods and many non-Fx Element methods support "method chaining" in that
 * they return the Element object itself as the method return value, it is not always possible to mix the two in a single
 * method chain.  The Fx methods use an internal effects queue so that each effect can be properly timed and sequenced.
 * Non-Fx methods, on the other hand, have no such internal queueing and will always execute immediately.  For this reason,
 * while it may be possible to mix certain Fx and non-Fx method calls in a single chain, it may not always provide the
 * expected results and should be done with care.  Also see <tt>{@link #callback}</tt>.</p><br/>
 *
 * <p><b><u>Anchor Options for Motion Effects</u></b></p>
 * <p>Motion effects support 8-way anchoring, meaning that you can choose one of 8 different anchor points on the Element
 * that will serve as either the start or end point of the animation.  Following are all of the supported anchor positions:</p>
<pre>
Value  Description
-----  -----------------------------
tl     The top left corner
t      The center of the top edge
tr     The top right corner
l      The center of the left edge
r      The center of the right edge
bl     The bottom left corner
b      The center of the bottom edge
br     The bottom right corner
</pre>
 * <b>Note</b>: some Fx methods accept specific custom config parameters.  The options shown in the Config Options
 * section below are common options that can be passed to any Fx method unless otherwise noted.</b>
 * 
 * @cfg {Function} callback A function called when the effect is finished.  Note that effects are queued internally by the
 * Fx class, so a callback is not required to specify another effect -- effects can simply be chained together
 * and called in sequence (see note for <b><u>Method Chaining</u></b> above), for example:<pre><code>
 * el.slideIn().highlight();
 * </code></pre>
 * The callback is intended for any additional code that should run once a particular effect has completed. The Element
 * being operated upon is passed as the first parameter.
 * 
 * @cfg {Object} scope The scope (<code>this</code> reference) in which the <tt>{@link #callback}</tt> function is executed. Defaults to the browser window.
 * 
 * @cfg {String} easing A valid Ext.lib.Easing value for the effect:</p><div class="mdetail-params"><ul>
 * <li><b><tt>backBoth</tt></b></li>
 * <li><b><tt>backIn</tt></b></li>
 * <li><b><tt>backOut</tt></b></li>
 * <li><b><tt>bounceBoth</tt></b></li>
 * <li><b><tt>bounceIn</tt></b></li>
 * <li><b><tt>bounceOut</tt></b></li>
 * <li><b><tt>easeBoth</tt></b></li>
 * <li><b><tt>easeBothStrong</tt></b></li>
 * <li><b><tt>easeIn</tt></b></li>
 * <li><b><tt>easeInStrong</tt></b></li>
 * <li><b><tt>easeNone</tt></b></li>
 * <li><b><tt>easeOut</tt></b></li>
 * <li><b><tt>easeOutStrong</tt></b></li>
 * <li><b><tt>elasticBoth</tt></b></li>
 * <li><b><tt>elasticIn</tt></b></li>
 * <li><b><tt>elasticOut</tt></b></li>
 * </ul></div>
 *
 * @cfg {String} afterCls A css class to apply after the effect
 * @cfg {Number} duration The length of time (in seconds) that the effect should last
 * 
 * @cfg {Number} endOpacity Only applicable for {@link #fadeIn} or {@link #fadeOut}, a number between
 * <tt>0</tt> and <tt>1</tt> inclusive to configure the ending opacity value.
 *  
 * @cfg {Boolean} remove Whether the Element should be removed from the DOM and destroyed after the effect finishes
 * @cfg {Boolean} useDisplay Whether to use the <i>display</i> CSS property instead of <i>visibility</i> when hiding Elements (only applies to 
 * effects that end with the element being visually hidden, ignored otherwise)
 * @cfg {String/Object/Function} afterStyle A style specification string, e.g. <tt>"width:100px"</tt>, or an object
 * in the form <tt>{width:"100px"}</tt>, or a function which returns such a specification that will be applied to the
 * Element after the effect finishes.
 * @cfg {Boolean} block Whether the effect should block other effects from queueing while it runs
 * @cfg {Boolean} concurrent Whether to allow subsequently-queued effects to run at the same time as the current effect, or to ensure that they run in sequence
 * @cfg {Boolean} stopFx Whether preceding effects should be stopped and removed before running current effect (only applies to non blocking effects)

 * @class Ext.Updater
 * @extends Ext.util.Observable
 * Provides AJAX-style update capabilities for Element objects.  Updater can be used to {@link #update}
 * an {@link Ext.Element} once, or you can use {@link #startAutoRefresh} to set up an auto-updating
 * {@link Ext.Element Element} on a specific interval.<br><br>
 * Usage:<br>
 * <pre><code>
 * var el = Ext.get("foo"); // Get Ext.Element object
 * var mgr = el.getUpdater();
 * mgr.update({
        url: "http://myserver.com/index.php",
        params: {
            param1: "foo",
            param2: "bar"
        }
 * });
 * ...
 * mgr.formUpdate("myFormId", "http://myserver.com/index.php");
 * <br>
 * // or directly (returns the same Updater instance)
 * var mgr = new Ext.Updater("myElementId");
 * mgr.startAutoRefresh(60, "http://myserver.com/index.php");
 * mgr.on("update", myFcnNeedsToKnow);
 * <br>
 * // short handed call directly from the element object
 * Ext.get("foo").load({
        url: "bar.php",
        scripts: true,
        params: "param1=foo&amp;param2=bar",
        text: "Loading Foo..."
 * });
 * </code></pre>
 * @constructor
 * Create new Updater directly.
 * @param {Mixed} el The element to update
 * @param {Boolean} forceNew (optional) By default the constructor checks to see if the passed element already
 * has an Updater and if it does it returns the same instance. This will skip that check (useful for extending this class).

 * <pre><code>
Date.patterns = {

 * @class Ext.util.DelayedTask
 * <p> The DelayedTask class provides a convenient way to "buffer" the execution of a method,
 * performing setTimeout where a new timeout cancels the old timeout. When called, the
 * task will wait the specified time period before executing. If durng that time period,
 * the task is called again, the original call will be cancelled. This continues so that
 * the function is only called a single time for each iteration.</p>
 * <p>This method is especially useful for things like detecting whether a user has finished
 * typing in a text field. An example would be performing validation on a keypress. You can
 * use this class to buffer the keypress events for a certain number of milliseconds, and
 * perform only if they stop for that amount of time.  Usage:</p><pre><code>
var task = new Ext.util.DelayedTask(function(){
    alert(Ext.getDom('myInputField').value.length);
});
// Wait 500ms before calling our function. If the user presses another key 
// during that 500ms, it will be cancelled and we'll wait another 500ms.
Ext.get('myInputField').on('keypress', function(){
    task.{@link #delay}(500); 
});
 * </code></pre> 
 * <p>Note that we are using a DelayedTask here to illustrate a point. The configuration
 * option <tt>buffer</tt> for {@link Ext.util.Observable#addListener addListener/on} will
 * also setup a delayed task for you to buffer events.</p>

 * @extends Ext.Template
 * <p>A template class that supports advanced functionality like:<div class="mdetail-params"><ul>
 * <li>Autofilling arrays using templates and sub-templates</li>
 * <li>Conditional processing with basic comparison operators</li>
 * <li>Basic math function support</li>
 * <li>Execute arbitrary inline code with special built-in template variables</li>
 * <li>Custom member functions</li>
 * <li>Many special tags and built-in operators that aren't defined as part of
 * the API, but are supported in the templates that can be created</li>
 * </ul></div></p>
 * <p>XTemplate provides the templating mechanism built into:<div class="mdetail-params"><ul>
 * <li>{@link Ext.DataView}</li>
 * <li>{@link Ext.ListView}</li>
 * <li>{@link Ext.form.ComboBox}</li>
 * <li>{@link Ext.grid.TemplateColumn}</li>
 * <li>{@link Ext.grid.GroupingView}</li>
 * <li>{@link Ext.menu.Item}</li>
 * <li>{@link Ext.layout.MenuLayout}</li>
 * <li>{@link Ext.ColorPalette}</li>
 * </ul></div></p>
 * 
 * <p>For example usage {@link #XTemplate see the constructor}.</p>  
 *   
 * @constructor
 * The {@link Ext.Template#Template Ext.Template constructor} describes
 * the acceptable parameters to pass to the constructor. The following
 * examples demonstrate all of the supported features.</p>
 * 
 * <div class="mdetail-params"><ul>
 * 
 * <li><b><u>Sample Data</u></b> 
 * <div class="sub-desc">
 * <p>This is the data object used for reference in each code example:</p>
 * <pre><code>
var data = {
    name: 'Jack Slocum',
    title: 'Lead Developer',
    company: 'Ext JS, LLC',
    email: 'jack@extjs.com',
    address: '4 Red Bulls Drive',
    city: 'Cleveland',
    state: 'Ohio',
    zip: '44102',
    drinks: ['Red Bull', 'Coffee', 'Water'],
    kids: [{
        name: 'Sara Grace',
        age:3
    },{
        name: 'Zachary',
        age:2
    },{
        name: 'John James',
        age:0
    }]
};
 * </code></pre>
 * </div>
 * </li>
 * 
 * 
 * <li><b><u>Auto filling of arrays</u></b> 
 * <div class="sub-desc">
 * <p>The <b><tt>tpl</tt></b> tag and the <b><tt>for</tt></b> operator are used
 * to process the provided data object:
 * <ul>
 * <li>If the value specified in <tt>for</tt> is an array, it will auto-fill,
 * repeating the template block inside the <tt>tpl</tt> tag for each item in the
 * array.</li>
 * <li>If <tt>for="."</tt> is specified, the data object provided is examined.</li>
 * <li>While processing an array, the special variable <tt>{#}</tt>
 * will provide the current array index + 1 (starts at 1, not 0).</li>
 * </ul>
 * </p>
 * <pre><code>
&lt;tpl <b>for</b>=".">...&lt;/tpl>       // loop through array at root node
&lt;tpl <b>for</b>="foo">...&lt;/tpl>     // loop through array at foo node
&lt;tpl <b>for</b>="foo.bar">...&lt;/tpl> // loop through array at foo.bar node
 * </code></pre>
 * Using the sample data above:
 * <pre><code>
var tpl = new Ext.XTemplate(
    '&lt;p>Kids: ',
    '&lt;tpl <b>for</b>=".">',       // process the data.kids node
        '&lt;p>{#}. {name}&lt;/p>',  // use current array index to autonumber
    '&lt;/tpl>&lt;/p>'
);
tpl.overwrite(panel.body, data.kids); // pass the kids property of the data object
 * </code></pre>
 * <p>An example illustrating how the <b><tt>for</tt></b> property can be leveraged
 * to access specified members of the provided data object to populate the template:</p>
 * <pre><code>
var tpl = new Ext.XTemplate(
    '&lt;p>Name: {name}&lt;/p>',
    '&lt;p>Title: {title}&lt;/p>',
    '&lt;p>Company: {company}&lt;/p>',
    '&lt;p>Kids: ',
    '&lt;tpl <b>for="kids"</b>>',     // interrogate the kids property within the data
        '&lt;p>{name}&lt;/p>',
    '&lt;/tpl>&lt;/p>'
);
tpl.overwrite(panel.body, data);  // pass the root node of the data object
 * </code></pre>
 * <p>Flat arrays that contain values (and not objects) can be auto-rendered
 * using the special <b><tt>{.}</tt></b> variable inside a loop.  This variable
 * will represent the value of the array at the current index:</p>
 * <pre><code>
var tpl = new Ext.XTemplate(
    '&lt;p>{name}\&#39;s favorite beverages:&lt;/p>',
    '&lt;tpl for="drinks">',
       '&lt;div> - {.}&lt;/div>',
    '&lt;/tpl>'
);
tpl.overwrite(panel.body, data);
 * </code></pre>
 * <p>When processing a sub-template, for example while looping through a child array,
 * you can access the parent object's members via the <b><tt>parent</tt></b> object:</p>
 * <pre><code>
var tpl = new Ext.XTemplate(
    '&lt;p>Name: {name}&lt;/p>',
    '&lt;p>Kids: ',
    '&lt;tpl for="kids">',
        '&lt;tpl if="age > 1">',
            '&lt;p>{name}&lt;/p>',
            '&lt;p>Dad: {<b>parent</b>.name}&lt;/p>',
        '&lt;/tpl>',
    '&lt;/tpl>&lt;/p>'
);
tpl.overwrite(panel.body, data);
 * </code></pre>
 * </div>
 * </li>
 * 
 * 
 * <li><b><u>Conditional processing with basic comparison operators</u></b> 
 * <div class="sub-desc">
 * <p>The <b><tt>tpl</tt></b> tag and the <b><tt>if</tt></b> operator are used
 * to provide conditional checks for deciding whether or not to render specific
 * parts of the template. Notes:<div class="sub-desc"><ul>
 * <li>Double quotes must be encoded if used within the conditional</li>
 * <li>There is no <tt>else</tt> operator &mdash; if needed, two opposite
 * <tt>if</tt> statements should be used.</li>
 * </ul></div>
 * <pre><code>
&lt;tpl if="age &gt; 1 &amp;&amp; age &lt; 10">Child&lt;/tpl>
&lt;tpl if="age >= 10 && age < 18">Teenager&lt;/tpl>
&lt;tpl <b>if</b>="this.isGirl(name)">...&lt;/tpl>
&lt;tpl <b>if</b>="id==\'download\'">...&lt;/tpl>
&lt;tpl <b>if</b>="needsIcon">&lt;img src="{icon}" class="{iconCls}"/>&lt;/tpl>
// no good:
&lt;tpl if="name == "Jack"">Hello&lt;/tpl>
// encode &#34; if it is part of the condition, e.g.
&lt;tpl if="name == &#38;quot;Jack&#38;quot;">Hello&lt;/tpl>
 * </code></pre>
 * Using the sample data above:
 * <pre><code>
var tpl = new Ext.XTemplate(
    '&lt;p>Name: {name}&lt;/p>',
    '&lt;p>Kids: ',
    '&lt;tpl for="kids">',
        '&lt;tpl if="age > 1">',
            '&lt;p>{name}&lt;/p>',
        '&lt;/tpl>',
    '&lt;/tpl>&lt;/p>'
);
tpl.overwrite(panel.body, data);
 * </code></pre>
 * </div>
 * </li>
 * 
 * 
 * <li><b><u>Basic math support</u></b> 
 * <div class="sub-desc">
 * <p>The following basic math operators may be applied directly on numeric
 * data values:</p><pre>
 * + - * /
 * </pre>
 * For example:
 * <pre><code>
var tpl = new Ext.XTemplate(
    '&lt;p>Name: {name}&lt;/p>',
    '&lt;p>Kids: ',
    '&lt;tpl for="kids">',
        '&lt;tpl if="age &amp;gt; 1">',  // <-- Note that the &gt; is encoded
            '&lt;p>{#}: {name}&lt;/p>',  // <-- Auto-number each item
            '&lt;p>In 5 Years: {age+5}&lt;/p>',  // <-- Basic math
            '&lt;p>Dad: {parent.name}&lt;/p>',
        '&lt;/tpl>',
    '&lt;/tpl>&lt;/p>'
);
tpl.overwrite(panel.body, data);
</code></pre>
 * </div>
 * </li>
 *
 * 
 * <li><b><u>Execute arbitrary inline code with special built-in template variables</u></b> 
 * <div class="sub-desc">
 * <p>Anything between <code>{[ ... ]}</code> is considered code to be executed
 * in the scope of the template. There are some special variables available in that code:
 * <ul>
 * <li><b><tt>values</tt></b>: The values in the current scope. If you are using
 * scope changing sub-templates, you can change what <tt>values</tt> is.</li>
 * <li><b><tt>parent</tt></b>: The scope (values) of the ancestor template.</li>
 * <li><b><tt>xindex</tt></b>: If you are in a looping template, the index of the
 * loop you are in (1-based).</li>
 * <li><b><tt>xcount</tt></b>: If you are in a looping template, the total length
 * of the array you are looping.</li>
 * <li><b><tt>fm</tt></b>: An alias for <tt>Ext.util.Format</tt>.</li>
 * </ul>
 * This example demonstrates basic row striping using an inline code block and the
 * <tt>xindex</tt> variable:</p>
 * <pre><code>
var tpl = new Ext.XTemplate(
    '&lt;p>Name: {name}&lt;/p>',
    '&lt;p>Company: {[values.company.toUpperCase() + ", " + values.title]}&lt;/p>',
    '&lt;p>Kids: ',
    '&lt;tpl for="kids">',
       '&lt;div class="{[xindex % 2 === 0 ? "even" : "odd"]}">',
        '{name}',
        '&lt;/div>',
    '&lt;/tpl>&lt;/p>'
);
tpl.overwrite(panel.body, data);
 * </code></pre>
 * </div>
 * </li>
 * 
 * <li><b><u>Template member functions</u></b> 
 * <div class="sub-desc">
 * <p>One or more member functions can be specified in a configuration
 * object passed into the XTemplate constructor for more complex processing:</p>
 * <pre><code>
var tpl = new Ext.XTemplate(
    '&lt;p>Name: {name}&lt;/p>',
    '&lt;p>Kids: ',
    '&lt;tpl for="kids">',
        '&lt;tpl if="this.isGirl(name)">',
            '&lt;p>Girl: {name} - {age}&lt;/p>',
        '&lt;/tpl>',
        // use opposite if statement to simulate 'else' processing:
        '&lt;tpl if="this.isGirl(name) == false">',
            '&lt;p>Boy: {name} - {age}&lt;/p>',
        '&lt;/tpl>',
        '&lt;tpl if="this.isBaby(age)">',
            '&lt;p>{name} is a baby!&lt;/p>',
        '&lt;/tpl>',
    '&lt;/tpl>&lt;/p>',
    {
        // XTemplate configuration:
        compiled: true,
        disableFormats: true,
        // member functions:
        isGirl: function(name){

 @class Ext.util.ClickRepeater
 @extends Ext.util.Observable

 A wrapper class which can be applied to any element. Fires a "click" event while the
 mouse is pressed. The interval between firings may be specified in the config but
 defaults to 20 milliseconds.

 Optionally, a CSS class may be applied to the element during the time it is pressed.

 @cfg {Mixed} el The element to act as a button.
 @cfg {Number} delay The initial delay before the repeating event begins firing.
 Similar to an autorepeat key delay.
 @cfg {Number} interval The interval between firings of the "click" event. Default 20 ms.
 @cfg {String} pressClass A CSS class name to be applied to the element while pressed.
 @cfg {Boolean} accelerate True if autorepeating should start slowly and accelerate.
           "interval" and "delay" are ignored.
 @cfg {Boolean} preventDefault True to prevent the default click event
 @cfg {Boolean} stopDefault True to stop the default click event
