fits a transfo to a std::list of Point pairs (p1,p2, the Point fields in StarMatch).
After the fit this(p1) yields approximately p2. The returned value is the sum of squared residuals. If you want to fit a partial transfo (e.g. such that this(T1(p1)) = T2(p2), use StarMatchList::applyTransfo beforehand.
