[Proj4j] Test data from GeoTools - further suggestions

[Martin Davis]

An interesting suggestion from Andrea Aime, the maintainer of the 
GeoTools CRS library.

Here is the GeoTools WKT parser:
http://svn.osgeo.org/geotools/branches/2.6.x/modules/library/referencing/src/main/java/org/geotools/referencing/wkt/Parser.java

Maybe you can adapt it or get inspiration for a version that builds
Proj4j objects?

Yeah, I'm not really fond of those scripts either, but they are there
and provide good guard against me messing with the referencing subsystem
(I'm the new mantainer, but nowhere near as good as Martin D. at it).
