     * @class Ext.QuickTips
     * Provides attractive and customizable tooltips for any element. The QuickTips
     * singleton is used to configure and manage tooltips globally for multiple elements
     * in a generic manner.  To create individual tooltips with maximum customizability,
     * you should consider either {@link Ext.Tip} or {@link Ext.ToolTip}.
     * Quicktips can be configured via tag attributes directly in markup, or by
     * registering quick tips programmatically via the {@link #register} method.
     * The singleton's instance of {@link Ext.QuickTip} is available via
     * {@link #getQuickTip}, and supports all the methods, and all the all the
     * configuration properties of Ext.QuickTip. These settings will apply to all
     * tooltips shown by the singleton.
     * Below is the summary of the configuration properties which can be used.
     * For detailed descriptions see {@link #getQuickTip}
     * QuickTips singleton configs (all are optional)
     * dismissDelay
     * hideDelay
     * maxWidth
     * minWidth
     * showDelay
     * trackMouse
     * Target element configs (optional unless otherwise noted)
     * autoHide
     * cls
     * dismissDelay (overrides singleton value)
     * target (required)
     * text (required)
     * title
     * width
     * Here is an example showing how some of these config options could be used:
     *
    // Init the singleton.  Any tag-based quick tips will start working.
    Ext.QuickTips.init();

    // Apply a set of config properties to the singleton
    Ext.apply(Ext.QuickTips.getQuickTip(), {
        maxWidth: 200,
        minWidth: 100,
        showDelay: 50,
        trackMouse: true
    });

    // Manually register a quick tip for a specific element
    Ext.QuickTips.register({
        target: 'my-div',
        title: 'My Tooltip',
        text: 'This tooltip was added in code',
        width: 100,
        dismissDelay: 20
    });

     * To register a quick tip in markup, you simply add one or more of the valid QuickTip attributes prefixed with
     * the ext: namespace.  The HTML element itself is automatically set as the quick tip target. Here is the summary
     * of supported attributes (optional unless otherwise noted):
     * hide: Specifying "user" is equivalent to setting autoHide = false.  Any other value will be the
     * same as autoHide = true.
     * qclass: A CSS class to be applied to the quick tip (equivalent to the 'cls' target element config).
     * qtip (required): The quick tip text (equivalent to the 'text' target element config).
     * qtitle: The quick tip title (equivalent to the 'title' target element config).
     * qwidth: The quick tip width (equivalent to the 'width' target element config).
     * Here is an example of configuring an HTML element to display a tooltip from markup:
     *
    // Add a quick tip to an HTML button
    <input type="button" value="OK" ext:qtitle="OK Button" ext:qwidth="100"
         ext:qtip="This is a quick tip from markup!"></input>

     * @singleton
