Class for a simple mapping implementing a generic AstrometryTransform.
It uses a template rather than a pointer so that the derived classes can use the specifics of the transform. The class simplePolyMapping overloads a few routines.

Actually applies the AstrometryMapping and evaluates the derivatives w.r.t the fitted parameters.
This is grouped into a single call because for most models, evaluating the derivatives w.r.T parameters is not much longer than just transforming

Print a string representation of the contents of this mapping, for debugging.
This string representation can be very verbose, as it contains all of the parameters of all of the transforms in this mapping.
