-NAME                            MOLLWEIDE
-
-PURPOSE:       Transforms input longitude and latitude to Easting and
-               Northing for the MOllweide projection.  The
-               longitude and latitude must be in radians.  The Easting
-               and Northing values will be returned in meters.
