Name: geographic
 
Purpose: Provides a "dummy" implementation of the geographic projection.
    Since the geographic projection is the base projection that everything
    goes through when being transformed, there isn't any transformation
    needed for it.

Name: geo_print_info
 
Purpose: Prints out the projection parameter information for the geographic
    projection (there aren't any).
