Details:

Currently Match only accepts a single aperture (error in 2D) for matching all
the objects. But it may be the case that different positions were calculated
with different levels of certainty. 

It would thus be useful if Match can also take an error column for positions
along each dimension as input, maybe called `--ccolerr1' and `--ccolerr2'. The
values in these colums can be used to make an object-specific aperture for
each searched match instead of using a single aperture for all.

This task was suggested by Leindert Boogaard.
