Some information that might be helpful in focussing development and 
testing efforts.

This is a list of all the projections used in the PROJ4 epsg catalog, 
and the number of CRSes each is used in. 

Notice that there aren't that many compared to the number of projections 
provided by PROJ4!.  My assumption is that this list reflects the 
real-world usage level of the various projections.
