A photometric transform, defined in terms of the input flux or magnitude.
Unit agnostic: a higher level Model must keep track of the units going into and out of of its Transforms.

return a copy (allocated by new) of the transformation.
Implemented in lsst::jointcal::MagnitudeTransformChebyshev, lsst::jointcal::FluxTransformChebyshev, lsst::jointcal::MagnitudeTransformSpatiallyInvariant, and lsst::jointcal::FluxTransformSpatiallyInvariant.
