Detailed Description

Memory management, portable types, math constants, and timing.

Author:: Pascal Getreuer <getreuer@gmail.com>

This file implements a function Clock, a timer with millisecond precision. In order to obtain timing at high resolution, platform- specific functions are needed:

On Windows systems, the GetSystemTime function is used.
On UNIX systems, the gettimeofday function is used.

This file attempts to detect whether the platform is Windows or UNIX and defines Clock accordingly.
