SUBROUTINES

   fwd_transform($lon(pdl), $lat(pdl), $params)
       Proj4 forward transformation $params is a string of the projection transformation parameters.

       Returns two pdls for x and y values respectively. The units are dependant on Proj4 behavior. They will be PDL->null if an error has
       occurred.

       BadDoc: Ignores bad elements of $lat and $lon, and sets the corresponding elements of $x and $y to BAD

   inv_transform($x(pdl), $y(pdl), $params)
       Proj4 inverse transformation $params is a string of the projection transformation parameters.

       Returns two pdls for lat and lon values respectively. The units are dependant on Proj4 behavior. They will be PDL->null if an error has
       occurred.

       BadDoc: Ignores bad elements of $lat and $lon, and sets the corresponding elements of $x and $y to BAD

   get_proj_info($params_string)
       Returns a string with information about what parameters proj will actually use, this includes defaults, and +init=file stuff. It's the same
       as running 'proj -v'. It uses the proj command line, so it might not work with all shells. I've tested it with bash.
