    /**
     * 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.dom.Element}. The methods from
     * these classes will be performed on all the elements in this collection.
     *
     * All methods return _this_ and can be chained.
     *
     * Usage:
     *
     *      var els = Ext.select("#some-el div.some-class", true);
     *      // or select directly from an existing element
     *      var el = Ext.get('some-el');
     *      el.select('div.some-class', true);
     *
     *      els.setWidth(100); // all elements become 100 width
     *      els.hide(true); // all elements fade out and hide
     *      // or
     *      els.setWidth(100).hide(true);
