[AstroPy] Cross matching two source lists

[Sergio Pascual]

Well, I don't know if it's exactly what you are looking for, but,
after some discussion in this list I created a package that
implementsthe Groth algorithm for catalogue matching:

A Pattern-Matching Algorithm for Two-Dimensional Coordinate Lists

The code is here: https://bitbucket.org/sergiopr/gmatch
