GeoAPI wrappers for Proj4J

[Martin Desruisseaux <ma...@geomatys.com>]

Hello all

For information, a pull request has been submitted to the PROJ4J project 
for adding GeoAPI wrappers in a `proj4j-geoapi` module. If accepted, 
that optional module would be part of the PROJ4J project and deployed 
together with PROJ4J releases, thus making easy to use PROJ4J behind 
GeoAPI interfaces. The core PROJ4J module is unchanged, the GeoAPI 
wrappers are optional.

Regarding the GeoAPI wrappers for GeoTools announced last Saturday, they 
have been deployed on a Maven repository. It would have been more 
convenient for users if that project was an optional module of GeoTools 
like above-cited optional module of PROJ4J, but it would need to be a 
request to GeoTools PMC coming from other volunteers than me (we would 
be happy to donate the code to OSGeo). In the meantime, the Maven 
coordinates are in the README file below:

Therefore, the list of known GeoAPI implementations providing 
referencing services is:

  * Apache SIS (implements GeoAPI directly)
  * GeoTools through `geoapi-geotools` wrappers
  * PROJ4J through `proj4j-geoapi` wrappers
  * PROJ through `PROJ-JNI` wrappers
  * NetCDF UCAR library through `geoapi-netcdf-java` wrappers

Hello all

Just a quick note for notifying that the GeoAPI wrappers for PROJ4J have 
been merged to the main branch of the PROJ4J project and a release is 
expected soon [1]. Thanks to Grigory Pomadchin for the review!
