    /**
     * All of the code for your public-facing JavaScript source
     * should reside in this file.
     *
     * Note: It has been assumed you will write jQuery code here, so the
     * $ function reference has been prepared for usage within the scope
     * of this function.
     *
     * This enables you to define handlers, for when the DOM is ready:
     *
     * $(function(){
     *
     * });
     *
     * When the window is loaded:
     *
     * $(window).on('load', function(){
     *
     * });
     *
     * ...and/or other possibilities.
     *
     * Ideally, it is not considered best practise to attach more than a
     * single DOM-ready or window-load handler for a particular page.
     * Although scripts in the WordPress core, Plugins and Themes may be
     * practising this, we should strive to set a better example in our own work.
