/**
 * @class Ext.ux.ButtonLockedToggle & Ext.ux.tbButtonLockedToggle
 * @extends Ext.Button
 * @description
 * The normal button, when enableToggle is used and toggleGroup is set correctly, still allows the user
 * to toggle off the toggled button by pressing on it. This class overrides the toggle-method so that
 * the toggled button is impossible to 'untoggle' other than programmatically or as a reaction
 * to any of the other buttons in the group getting toggled on.
 *
 * Toggle is by the way a very strange word when you repeat it enough.
 *
 * @author www.steinarmyhre.com
 * @constructor
 * Identical to Ext.Button and/or Ext.Toolbar.Button except that enableToggle is true by default.
 * @param (Object/Array) config A config object
