Class CMProj4Grid extends CMProjector
CMProj4Grid
Projects data based on a grid. This class uses a URL to a Proj4 grid file as created
by the associated Python script. This file is used when the user just wants to specify
a single projection grid. Otherwise, CMProj4WebService should be used which inherits
from this class and allows various settings to be specified and a web service call will
then produce a new grid for those settings.
