Brad makes a good point... matching should be done based on date
difference, not on matching year, month, or day.

I just looked at src/plugins/tool/FindDupes.py and it compares dates
in the most basic way. This tool should be revised to use many of the
more sophisticated tools that we now have in Gramps.

Matching could be one of the most useful tools in Gramps, but this one
needs some work.
