A matrix math class for 4x4 matrices of doubles.
This class provides access to Maya's internal matrix math library allowing matrices to be handled easily, and in a manner compatible with internal Maya data structures.
All methods that query the matrix are threadsafe, all methods that modify the matrix are not threadsafe.
