* @class YAHOO.ext.grid.DefaultDataModel
* This is the default implementation of a DataModel used by the Grid. It works
* with multi-dimensional array based data. Using the event system in the base class
* {@link YAHOO.ext.grid.AbstractDataModel}, all updates to this DataModel are automatically
* reflected in the user interface.
* &lt;br&gt;Usage:&lt;br&gt;
* &lt;pre&gt;&lt;code&gt;
* var myData = [
[&quot;MSFT&quot;,&quot;Microsoft Corporation&quot;, &quot;314,571.156&quot;, &quot;32,187.000&quot;, &quot;55000&quot;],
[&quot;ORCL&quot;, &quot;Oracle Corporation&quot;, &quot;62,615.266&quot;, &quot;9,519.000&quot;, &quot;40650&quot;]
* ];
* var dataModel = new YAHOO.ext.grid.DefaultDataModel(myData);
* &lt;/code&gt;&lt;/pre&gt;
* @extends YAHOO.ext.grid.AbstractDataModel
* @constructor
