class Geo::Matrix

This class uses column major ordering. That is to say elements from the same column are adjacent in memory.

When representing geometric transformations, we transform a point by representing it as a column vector. For convenience, a Matrix is represented as a union of different types so that matrix elements can be referenced by named column, column index, element name, element index. Basic wrapper around a critical section object. Required to protect code paths that are not multi-thread safe.
