    /**
     * Creates a debouncer if no debouncer is passed as a parameter
     * or it cancels an active debouncer otherwise. The following
     * example shows how a debouncer can be called multiple times within a
     * microtask and "debounced" such that the provided callback function is
     * called once. Add this method to a custom element:
     *
     * _debounceWork() {
     *   this._debounceJob = Polymer.Debouncer.debounce(this._debounceJob,
     *       Polymer.Async.microTask, () => {
     *     this._doWork();
     *   });
     * }
     *
     * If the `_debounceWork` method is called multiple times within the same
     * microtask, the `_doWork` function will be called only once at the next
     * microtask checkpoint.
     *
     * Note: In testing it is often convenient to avoid asynchrony. To accomplish
     * this with a debouncer, you can use `Polymer.enqueueDebouncer` and
     * `Polymer.flush`. For example, extend the above example by adding
     * `Polymer.enqueueDebouncer(this._debounceJob)` at the end of the
     * `_debounceWork` method. Then in a test, call `Polymer.flush` to ensure
     * the debouncer has completed.
     *
     * @param debouncer Debouncer object.
     * @param asyncModule Object with Async interface
     * @param callback Callback to run.
     * @returns Returns a debouncer object.
