Completed basic threading

5 threads concurrently execute now. Need some sort of heavy processing
to run....
Added logging to file bench_log (ignored from git)
Redid threading

For some reason with thread concurrency, variables were being past in to
threads as the same value. Rewrote threading logic to properly get
values
Added some comments
Completed thread benchmarking

Thread benchmarking completed with larger numbers to be primed.
Changed usage to run both tests sequentially.
Increased the size of the numbers to be primed to actually make a
computer calculate them with some time.
