Some prime number research, providing the ability to select precision and see the tradeoffs on speed. Do everything to make the computation fast. Yes, I feel dirty about the sighandler stuff.

latest prime-hexagon prime generation with new/better primesieve-python interface
# 10B values using new prime generation interface directly to numpy arrays
# total time - 1m:43sec for the entire calculation.
# prime generation was only 10 sec.
