Matrix comparison operators

[jonathansty]

Matrices currently do not have any comparison operators defined for them. I can get around it by writing my own operators manually but it would be nice if these were built-in in hlslpp.

Build output

@jonathansty I have implemented comparison operators for the square matrices and added any/all functions should you need to check whether all or any of the components are != 0. I'll get around to adding them for all other matrices at some point.

Fixed via ccaa72c
