Helmert2DWithZOffset Class

An affine transformation with an additional Z Offset. The equations are: given a = scale * cos(rotation) and b = scale * sin(rotation) X = a * x - b * y + translationX Y = b * x + a * y + translationY Z = z + translationZ

Note that the class only implements the definition and not the operation.
