     * @class Ext.grid.GridPanel
     * @extends Ext.Panel
     * This class represents the primary interface of a component based grid control to represent data
     * in a tabular format of rows and columns. The GridPanel is composed of the following:
     *
     * {@link Ext.data.Store Store} : The Model holding the data records (rows)
     *
     * {@link Ext.grid.ColumnModel Column model} : Column makeup
     *
     * {@link Ext.grid.GridView View} : Encapsulates the user interface
     *
     * {@link Ext.grid.AbstractSelectionModel selection model} : Selection behavior
     *
     *
     * Example usage:
     *
    var grid = new Ext.grid.GridPanel({
        {@link #store}: new {@link Ext.data.Store}({
            {@link Ext.data.Store#autoDestroy autoDestroy}: true,
            {@link Ext.data.Store#reader reader}: reader,
            {@link Ext.data.Store#data data}: xg.dummyData
        }),
        {@link #colModel}: new {@link Ext.grid.ColumnModel}({
            {@link Ext.grid.ColumnModel#defaults defaults}: {
                width: 120,
                sortable: true
            },
            {@link Ext.grid.ColumnModel#columns columns}: [
                {id: 'company', header: 'Company', width: 200, sortable: true, dataIndex: 'company'},
                {header: 'Price', renderer: Ext.util.Format.usMoney, dataIndex: 'price'},

                {
                    header: 'Last Updated', width: 135, dataIndex: 'lastChange',
                    xtype: 'datecolumn', format: 'M d, Y'
                }

     * Notes:
     *
     * Although this class inherits many configuration options from base classes, some of them
     * (such as autoScroll, autoWidth, layout, items, etc) are not used by this class, and will
     * have no effect.
     * A grid requires a width in which to scroll its columns, and a height in which to
     * scroll its rows. These dimensions can either be set explicitly through the
     * {@link Ext.BoxComponent#height height} and {@link Ext.BoxComponent#width width}
     * configuration options or implicitly set by using the grid as a child item of a
     * {@link Ext.Container Container} which will have a {@link Ext.Container#layout layout manager}
     * provide the sizing of its child items (for example the Container of the Grid may specify
     * {@link Ext.Container#layout layout}:'fit').
     * To access the data in a Grid, it is necessary to use the data model encapsulated
     * by the {@link #store Store}. See the {@link #cellclick} event for more details.
