Task Master helps run ASYNC tasks.
Task Master allows a Runnable task to be submitted for execution and returns a Future representing that task. The
Future's get method will return the given result upon successful completion.
As Web applications require a Future implementation that can be serializable, the Task Master has a custom
interface of TaskFuture that implements both Future and Serializable. It does not make sense for a Future
to be serilaizable as it is running on a specific thread on a particular server. To allow a Web Application to keep a
reference to the Future, the default implementation of TaskFuture (ie TaskFutureWrapper) wraps the future by
putting the Future on a cache and holding onto the cache key that is serializable.
The ServiceHelper class helps applications submit ASYNC service calls.
