Implement new tests for projection between CRS defined with OGC WKT.
Note : the projections using nadgrids are not working, because OGC WKT do not recognize nadgrids.
Split the SpecialCoordinateTransformTest file into two files :
one contains tests using PRJ to define the CRS (PRJCoordinateTransformationTest),
the other contains tests using uncommon CRS not defined in registries.
Improve the PrjValueParameters class using PRJ and increment the version of the library.
Add Javadoc in PrjValueParameters class.
