Detailed Description
All world tasks must be derived from this public interface.
Multiple worlds with independent queues feed tasks into shared task pool that is mapped to the H/W.
For simplicity and backward compatibility we maintain two run interfaces but new code should adopt the multithreaded interface
run(World&) - the user implements this for a single-threaded task
run(World&, const TaskThreadEnv&) - the user implements this for a multi-threaded task.

Override this method to implement a multi-threaded task.
info.nthread() will be the number of threads collaborating on this task
info.id() will be the index of the current thread id=0,...,nthread-1
info.barrier() will be a barrier for all of the threads, and returns true for the last thread to enter the barrier (other threads get false)
