+/**
+ * InteractionManager allows long-running work to be scheduled after any
+ * interactions/animations have completed. In particular, this allows JavaScript
+ * animations to run smoothly.
+ *
+ * Applications can schedule tasks to run after interactions with the following:
+ *
+ * ```
+ * InteractionManager.runAfterInteractions(() => {
+ *   // ...long-running synchronous task...
+ * });
+ * ```
+ *
+ * Compare this to other scheduling alternatives:
+ *
+ * - requestAnimationFrame(): for code that animates a view over time.
+ * - setImmediate/setTimeout(): run code later, note this may delay animations.
+ * - runAfterInteractions(): run code later, without delaying active animations.
+ *
+ * The touch handling system considers one or more active touches to be an
+ * 'interaction' and will delay `runAfterInteractions()` callbacks until all
+ * touches have ended or been cancelled.
+ *
+ * InteractionManager also allows applications to register animations by
+ * creating an interaction 'handle' on animation start, and clearing it upon
+ * completion:
+ *
+ * ```
+ * var handle = InteractionManager.createInteractionHandle();
+ * // run animation... (`runAfterInteractions` tasks are queued)
+ * // later, on animation completion:
+ * InteractionManager.clearInteractionHandle(handle);
+ * // queued tasks run if all handles were cleared
+ * ```
+ *
+ * `runAfterInteractions` takes either a plain callback function, or a
+ * `PromiseTask` object with a `gen` method that returns a `Promise`.  If a
+ * `PromiseTask` is supplied, then it is fully resolved (including asynchronous
+ * dependencies that also schedule more tasks via `runAfterInteractions`) before
+ * starting on the next task that might have been queued up synchronously
+ * earlier.
+ *
+ * By default, queued tasks are executed together in a loop in one
+ * `setImmediate` batch. If `setDeadline` is called with a positive number, then
+ * tasks will only be executed until the deadline (in terms of js event loop run
+ * time) approaches, at which point execution will yield via setTimeout,
+ * allowing events such as touches to start interactions and block queued tasks
+ * from executing, making apps more responsive.
