Detailed Description

4x4 Matrix.

Author:: Sean O'Neil

This class implements a 4x4 matrix. Several functions and operators are defined to make working with matrices easier. The values are kept in column- major order to make it easier to use with OpenGL. For performance reasons, most of the functions assume that all matrices are orthogonal, which means the bottom row is [ 0 0 0 1 ]. Since I plan to use the GL_PROJECTION matrix to handle the projection matrix, I should never need to use any other kind of matrix, and I get a decent performance boost by ignoring the bottom row.

Note: This class is not templatized because integral data types don't make sense and there's no need for double-precision.
