 It would be possible to automatically set the bounds for the new map after
 scanning the data, but as there is no associated resolution in the data
 you have to use whatever the current region settings are, and then code in
 a 'g.region -a' approach or not. At which point before running the module
 for the final product you have to scan the data and run 'g.region res= -a'
 and spend a little time thinking about the region size anyway. Or if you
 don't want to code in -a (it's problematic enough in g.region already), be
 content with it automatically using some haywire resolution setting, which
 I am not. The bin size is a critical part of what the module does and
 fundamental to the meaning of the results.
