How do I add a new projection to CSMap?  Specifically, the spherical  
mercator projection used by the commercial web mapping folks:

PROJCS["unnamed",GEOGCS["unnamed  
ellipse",DATUM["unknown",SPHEROID["unnamed", 
6378137,0]],PRIMEM["Greenwich",0],UNIT["degree", 
0.0174532925199433 
]],PROJECTION["Mercator_2SP"],PARAMETER["standard_parallel_1", 
0],PARAMETER["central_meridian",0],PARAMETER["false_easting", 
0],PARAMETER["false_northing",0],UNIT["Meter", 
1],EXTENSION["PROJ4","+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0  
+lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +wktext   
+no_defs"]]

Cheers

Paul
