/*!
 *
 * This library has been modified! This function has been changed: mouseProto._mouseInit
 *
 * Original Version:
 *
 *     mouseProto._mouseInit = function () {
 *   
 *       var self = this;
 *
 *       // Delegate the touch handlers to the widget's element
 *       self.element.bind({
 *         touchstart: $.proxy(self, '_touchStart'),
 *         touchmove: $.proxy(self, '_touchMove'),
 *         touchend: $.proxy(self, '_touchEnd')
 *         });
 *
 *       // Call the original $.ui.mouse init method
 *       _mouseInit.call(self);
 *     };
 *
 * 
 * New Version:
 * 
 *     mouseProto._mouseInit = function () {
 *
 *        var self = this;
 *
 *        // Delegate the touch handlers to the widget's element
 *        self.element
 *           .bind('taphold', $.proxy(self, '_touchStart'))   // IMPORTANT!MOD FOR TAPHOLD TO START SORTABLE
 *           .bind('touchmove', $.proxy(self, '_touchMove'))
 *           .bind('touchend', $.proxy(self, '_touchEnd'));
 *
 *         // Call the original $.ui.mouse init method
 *         _mouseInit.call(self);
 *     };  
 *
 * Why?
 *
 *  The original version mapped any tap start to a click. This means that you weren't able to scroll through
 *  the sortable on a mobile device, as every attempt to scroll was intercepted as a click.
