Matrix class

[Steven Miclette]

Assignment 2 seems mostly based around using matrices. I remembered a
reference to a Matrix4x4 class in the Assignment 1 description, but I
couldn't find any other reference to it.

Does this class actually exist, should we look for a separate matrix
library, or are we expected to write our own matrix math functions?

[Alex Keursten]

In the file viewer.hpp there is
Matrix4x4 m_projection;

so I imagine we are supposed to use the Matrix4x4 class

This system does focus on matrices. You are not expected to use a
separate matrix library and not suggested. The available Matrix
materials are located in the algebra.cpp file, and you are encouraged
to extend it as you see fit (however it should not be required).
