Module hektor::mat4

Module for 4x4 Matrices.

A 4x4 matrix is needed for certain transformations on 3D vectors:

• The 3D vector is promoted to a 4D vector (generally with a w component of 1.0)
• The 4D vector is multiplied on the right by the 4x4 matrix.
• The resulting 4D vector is turned back into a 3D vector by dividing x, y, and z by the w component (which is why 1.0 is considered the default).

Because we usually care quite a bit about our ability to manipulate 3D vectors/points, the Mat4 type is used much more than any other matrix.
