Generic Multi-dimensional CoordTransformation class

Description

The goal is to make a MxN transformation matrix that can take a coordinate in M dimensions and convert it to another space in N dimensions. The types of conversions to account for are:

  • Simple rotation matrix
  • Affine Transformation = linear transform such as a rotation + a translation
  • Projection into lower dimensions, for example taking a 2D slice out of 3D data.

The class will be templated by two parameters (# of in/out dimensions) in an effort to make it most efficient.
