 * @brief The TaskExecutor class

 * The user should sublass ControllableTask, implement background routine which checks sometimes
 * method shouldRun() of TaskControl instance passed to run(TaskControl&) and then use it like:
 *
 * QFututre<int> futureValue = TaskExecutor::run(new SomeControllableTask(inputForThatTask));
 *
 * Then she may cancel it by calling futureValue.cancel(), bearing in mind that cancellation is
 * graceful and not immediate.
