/**
 * This route executes "back" and "next" handler on the next run-loop
 * Reason: It's done like this, because in general transitions have highest priority in the Ember run-loop
 * So, CP's and observers for <code>App.router.backBtnClickInProgress</code> and <code>App.router.nextBtnClickInProgress</code>
 * will be triggered after "back" or "next" are complete and not before them.
 * It's more important for "back", because usually it doesn't do any requests that may cause a little delay for run loops
 * <code>Em.run.next</code> is used to avoid this
 *
 * Example:
 * <pre>
 *   App.Step2Route = App.StepRoute.extend({
 *
 *    route: '/step2',
 *
 *    connectOutlets: function (router, context) {
 *      // some code
 *    },
 *
 *    nextTransition: function (router) {
 *      router.transitionTo('step3');
 *    },
 *
 *    backTransition: function (router) {
 *      router.transitionTo('step1');
 *    }
 *
 *   });
 * </pre>
 * In this case both <code>transitionTo</code> will be executed in the next run loop after loop where "next" or "back" were called
 * <b>IMPORTANT!</b> Flags <code>App.router.backBtnClickInProgress</code> and <code>App.router.nextBtnClickInProgress</code> are set to <code>true</code>
 * in the "back" and "next". Be sure to set them <code>false</code> when needed
