CompareNets.m
This routine is used to look for the nearest sensors between two
configuration files (CartAscii format). For each one of the files in the dest config
(less sensors), the nearest source config sensor is found. No repetitions
are allowed (i.e., at the end the routine returns as many sensors as
the dest file).
After calculations, the program stores in a file an array, with numbers which
identify the number of sensors in the source config which are closest
to one of the dest config.
