Clean identifiers in VerticalTransformTest class.
Handle transformations between CompoundCRS and Geographic3DCRS.
The CRSHelper now creates Geographic3DCRS instead of Geographic2DCRS when the OGC WKT defines 3 axes.
Replace all the method registering and getting objects from their Identifier with one unique method in IdentifiableComponent.
Fix a bug in the recognition of projection parameters' values in an OGC WKT.
Also fix an error in the PrjWriter and in the Ellipsoid javadoc.
Correct the authorities in OGC WKTs used in VericalTransformTest.
Re-organize methods between AbstractDatum and GeodeticDatum.
Some methods that could be use only for GeodeticDatum were defined in AbstractDatum. It's clearer now.
Improve the CoordinateOperationFactory class by easing the management of CompoundCRS.
Fix a bug in SevenParameterTransformation class.
Add a test for the transformation between CompoundCRS and GeocentricCRS in VerticalTransform.
Slightly improve the toGeographicCoordinateConverter and the fromGeographicCoordinateConverter by using grids.
Improve the faculty of PrjParser to recognize whether a WKT define a CRS properly or not.
For instance it now checks if, for a CompoundCRS, the WKT define one and only one VerticalCRS and one and only one horizontal CRS.
Fix an error in toWKT method of SevenParameterTransformation and clean some files.
Modify the way to get WKT String from CTS component.
Each concerned class now has its own method toWKT() method.
Improve CTS to read NAD27 and NAD83 registries.
