[PROJ] Adding new projection to Proj4

I think Alessandro was proposing to add a new "projection method" (i.e. 
another set of mathematical formulas for doing the projection). This is 
a different work than assigning an EPSG code, which is more about 
setting parameter values to use with pre-existing formulas. If this is 
the case, then Alessandro's proposal and EPSG change request would be 
orthogonal tasks.
