If left->composeAndReduce(right)
returns NULL, build a AstrometryTransformComposition and return it. This routine implements "run-time" compositions. When there is a possible "reduction" (e.g. compositions of polynomials), compose detects it and returns a genuine AstrometryTransform.

The found transformation is a field of the returned object, as well as the star pairs (the matches) that were constructed. (see StarMatchList class definition for more details). The various cuts are contained in conditions (see listmatch.h) for its contents. This routine searches a transformation that involves a shift and a rotation.

A std::list of star matches,.
To be used as the argument to AstrometryTransform::fit routines. There is as well a StarMatch::fit routine which fits a polynomial by default, although the transform may be user-provided. The StarMatchList::refineTransform is a convenient tool to reject outliers. Given two catalogs, one can assemble a StarMatchList using utilities such as listMatchCollect. StarMatchList's have write capabilities. NStarMatchList is a generalization of this 2-match to n-matches.
