     * This class encapsulates a collection of DOM elements, providing methods to filter
     * members, or to perform collective actions upon the whole set.
     * Although they are not listed, this class supports all of the methods of {@link Ext.Element} and
     * {@link Ext.Fx}. The methods from these classes will be performed on all the elements in this collection.
     * Example:
    var els = Ext.select("#some-el div.some-class");
    // or select directly from an existing element
    var el = Ext.get('some-el');
    el.select('div.some-class');

    els.setWidth(100); // all elements become 100 width
    els.hide(true); // all elements fade out and hide
    // or
    els.setWidth(100).hide(true);
