  HandmadeMath.h v0.1

  This is a single header file with a bunch of useful functions for 
  basic game math operations.
  ==========================================================================
  You MUST

     #define HANDMADE_MATH_IMPLEMENTATION

  in EXACTLY one C or C++ file that includes this header, BEFORE the
  include, like this:

     #define HANDMADE_MATH_IMPLEMENTATION
     #include "HandmadeMath.h"

  All other files should just #include "HandmadeMath.h" without the #define.
  ==========================================================================

  For overloaded, and operator overloaded versions of the base C functions.
  You MUST

  #define HANDMADE_MATH_CPP_MODE

  in EXACTLY one C or C++ file that includes this header, BEFORE the
  include, like this:

     #define HANDMADE_MATH_IMPLEMENTATION
     #define HANDMADE_MATH_CPP_MODE
     #include "HandmadeMath.h"

  All other files should just #include "HandmadeMath.h" without the #define.
