// Note: No conflict function
 
// This function must be called after including the jQuery javascript file, but before including any other conflicting library,
// and also before actually that other conflicting library gets used, in case jQuery is included last. noConflict can be called at
// the end of the jQuery.js file to globally disable the $() jQuery alias. jQuery.noConflict returns a reference to jQuery, so it
// can be used to override the $() alias of the jQuery object.
// Use jQuery via jQuery(...)
//jQuery.noConflict();
