Extends one class to create a subclass and optionally overrides members with the passed literal. This method * also adds the function "override()" to the subclass that can be used to override members of the class.

* For example, to create a subclass of Ext GridPanel: *

MyGridPanel = Ext.extend(Ext.grid.GridPanel, {
    constructor: function(config) {

//      Create configuration for this Grid.
        var store = new Ext.data.Store({...});
        var colModel = new Ext.grid.ColumnModel({...});

//      Create a new config object containing our computed properties
//      *plus* whatever was in the config parameter.
        config = Ext.apply({
            store: store,
            colModel: colModel
        }, config);

        MyGridPanel.superclass.constructor.call(this, config);

//      Your postprocessing here
    },

    yourMethod: function() {
        // etc.
    }
});
* *

This function also supports a 3-argument call in which the subclass's constructor is * passed as an argument. In this form, the parameters are as follows:

*
* * @param {Function} superclass The constructor of class being extended. * @param {Object} overrides

A literal with members which are copied into the subclass's * prototype, and are therefore shared between all instances of the new class.

*

This may contain a special member named constructor. This is used * to define the constructor of the new class, and is returned. If this property is * not specified, a constructor is generated and returned which just calls the * superclass's constructor passing on its parameters.

*

It is essential that you call the superclass constructor in any provided constructor. See example code.
