Removed README (moved to README.md in previous commit, I just forgot to commit this being deleted)
Added _basic_ multiprocessing support. The current implementation
doesn't actually do anything in parallel, but it does dispatch each
trial in a new process.

TODO: Add timing and logging capabilities so we can measure the
performance of multiprocessing compared to the current sequential
simulation.
Added basic timing and logging functionality.
Added full multiprocessing support; processes are now dispatched on each core. However, multiprocessing is currently slower than sequential processing.
