Moved away from std::async and std::future as the underlying mechnism for the thread pool device. On several platforms, the functions passed to std::async are not scheduled in the order in which they are given to std::async, which leads to massive performance issues in the contraction code.
...
Instead we now have a custom thread pool that ensures that the functions are picked up by the threads in the pool in the order in which they are enqueued in the pool.

Improved the tensor random number generators:
...
* Use a mersenne twister whenebver possible instead of the default entropy source since the default one isn't very good at all.
* Added the ability to seed the generators with a time based seed to make them non-deterministic.
