Matrices

My work this week has been on the Matrix class for my software renderer. Much like the Vector class, it currently has most of the basic functions for Matrix arithmetic as well as building matrices. However it is missing functionality for creating view and projection matrices which will be added soon and give me the ability to draw some nice perspective 3d graphics from some basic vectors with GDI.

I've also created a static variable within the class to hold the identity matrix which will come in useful creating matrices from it. As to be expected there's also a method to output a string to console of the value of the Matrix.
