basic game math operations.

All other files should just #include "HandmadeMath.h" without the #define.
==========================================================================
To Disable the CRT, you MUST
#define HMM_SINF MySinF
#define HMM_COSF MyCosF
#define HMM_TANF MyTanF
Provide your own implementations of SinF, CosF, and TanF
in EXACTLY one C or C++ file that includes this header, BEFORE the
include, like this:
#define HMM_SINF MySinF
#define HMM_COSF MyCosF
#define HMM_TANF MyTanF
#define HANDMADE_MATH_IMPLEMENTATION
#define HANDMADE_MATH_CPP_MODE
#include "HandmadeMath.h"
If you do not define these HandmadeMath.h will use version the version
of these function that are provided by the CRT.
