/**
* @class Ext.grid.EditorGridPanel
* @extends Ext.grid.GridPanel
* This class extends the GridPanel to provide cell editing on selected columns.
* The editable columns are specified by providing an {@link Ext.grid.ColumnModel#editor editor}
* in the column configuration.
* Editability of columns may be controlled programatically by inserting an implementation
* of {@link Ext.grid.ColumnModel#isCellEditable isCellEditable} into your ColumnModel.
* Editing is performed on the value of the field specified by the column's
* {@link Ext.grid.ColumnModel#dataIndex dataIndex} in the backing {@link Ext.data.Store Store}
* (so if you are using a {@link Ext.grid.ColumnModel#setRenderer renderer} in order to display
* transformed data, this must be accounted for).
* If a value-to-description mapping is used to render a column, then a {Ext.form.Field#ComboBox ComboBox}
* which uses the same {@link Ext.form.Field#valueField value}-to-{@link Ext.form.Field#displayFieldField description}
* mapping would be an appropriate editor.
* If there is a more complex mismatch between the visible data in the grid, and the editable data in
* the {@link Edt.data.Store Store}, then code to transform the data both before and after editing can be
* injected using the {@link #beforeedit} and {@link #afteredit} events.
* @constructor
* @param {Object} config The config object
