[MetaCRS] Directory structure for CSV Test data files

[Martin Desruisseaux]

Thanks Frank for the motion :)

For the next step, do we setup the directory structure on SVN as a Maven project 
even if it has no Java files? It would allow us to deploy the test data files on 
the OSGEO Maven repository. C/C++ projects could use a direct URL to the JAR 
file and treat that has an ordinary ZIP file, or those who use SVN could 
"inject" a copy of the test data file (without the Maven-specific stuff) in 
their own source tree using the "svn:external" SVN property.

Or is there any other proposal?
