* development IDEs. Each row in the grid represents a property of some object, and the data is stored
* as a set of name/value pairs in {@link Ext.grid.property.Property Properties}. Example usage:
*
* @example
* Ext.create('Ext.grid.property.Grid', {
* title: 'Properties Grid',
* width: 300,
* renderTo: Ext.getBody(),
* source: {
* "(name)": "My Object",
* "Created": Ext.Date.parse('10/15/2006', 'm/d/Y'),
* "Available": false,
* "Version": 0.01,
* "Description": "A test object"
* }
