Hi,

Cool, a new projection. Thank you John.

I took a look at the code and have a few minor comments. (I have not run
it, as I am still setting up java stuff after doing an operating system
re-install).

1) Plate Carree can be added to the list of NamedIdentifiers (note, this
is what esri calls it)

2) Since these are the spherical equations,
Provider.createMathTransform() should check that the semi-major and
minor axises are equal. See the orthographic projection for an example.

3) Esri does not include a latitude of origin parameter (they probably
assume it is 0 for the equirectangular case. This is not a problem, but
may create some compatibility issues in the future.

I not done any geotools development over the last few months, but will
try to at least create a set of test points to compare to esri's
implementation. This will at least get me into the development mood (and
force me to learn eclipse).

Rueben
