     * @ngdoc service
     * @name $interval
     *
     * @description
     * AngularJS's wrapper for `window.setInterval`. The `fn` function is executed every `delay`
     * milliseconds.
     *
     * The return value of registering an interval function is a promise. This promise will be
     * notified upon each tick of the interval, and will be resolved after `count` iterations, or
     * run indefinitely if `count` is not defined. The value of the notification will be the
     * number of iterations that have run.
     * To cancel an interval, call `$interval.cancel(promise)`.
     *
     * In tests you can use {@link ngMock.$interval#flush `$interval.flush(millis)`} to
     * move forward by `millis` milliseconds and trigger any functions scheduled to run in that
     * time.
     *
     * <div class="alert alert-warning">
     * **Note**: Intervals created by this service must be explicitly destroyed when you are finished
     * with them.  In particular they are not automatically destroyed when a controller's scope or a
     * directive's element are destroyed.
     * You should take this into consideration and make sure to always cancel the interval at the
     * appropriate moment.  See the example below for more details on how and when to do this.
     * </div>
     *
     * @param {function()} fn A function that should be called repeatedly. If no additional arguments
     *   are passed (see below), the function is called with the current iteration count.
     * @param {number} delay Number of milliseconds between each function call.
     * @param {number=} [count=0] Number of times to repeat. If not set, or 0, will repeat
     *   indefinitely.
     * @param {boolean=} [invokeApply=true] If set to `false` skips model dirty checking, otherwise
     *   will invoke `fn` within the {@link ng.$rootScope.Scope#$apply $apply} block.
     * @param {...*=} Pass additional parameters to the executed function.
     * @returns {promise} A promise which will be notified on each iteration. It will resolve once all iterations of the interval complete.
