[MetaCRS] Adding Projection Classes to Proj4js

[billinb]

Did this ever get finished? I just came across this problem today. I can work
around it by using AJAX to get to the server and have proj4 do the
transformation, but I would rather get it working in proj4js. Are there any
plans to get it in? Do you need help finishing it? I don't know how to do
the forward and reverse transformation on an ellipsoid but I could
potentially take a look at the proj4 code. I could also take a look at
writing the unit tests.

Thanks,
 Brendan
