hitimes 0.4.1

Hitimes is a fast, high resolution timer library for recording performance metrics. It uses the appropriate C method calls for each system to get the highest granularity time increments possible. It currently supports any system with the POSIX call clock_gettime(), Mac OS X and Windows. Using Hitimes can be faster than using a series of Time.new calls, and it will have a much higher granularity. It is definitely faster than using Process.times.
