 * can also be created explicitly as shwon below.  Example usage:
 *

var rec = new Ext.grid.PropertyRecord({
    name: 'Birthday',

});
// Add record to an already populated grid

 * @constructor
 * @param {Object} config A data object in the format: {name: [name], value: [value]}.  The specified value's type
 * will be read automatically by the grid to determine the type of editor to use when displaying it.
