+// a set of routines that let you do common 3d math
+// operations without any vector, matrix, or quaternion
+// classes or templates.
+//
+// a vector (or point) is a 'NxF32 *' to 3 floating point numbers.
+// a matrix is a 'NxF32 *' to an array of 16 floating point numbers representing a 4x4 transformation matrix compatible with D3D or OGL
+// a quaternion is a 'NxF32 *' to 4 floats representing a quaternion x,y,z,w
