Full-featured command line ready for tests

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

Hello all

The command-line tools now support writing ISO 19139 XML documents. The 
binary is built by Jenkins [1], so testers don't have to build it 
locally. The command for unpacking is the same than in previous email 
[2]. Usage is:

java -jar sis.jar metadata <netcdf-file-or-URL> --format XML

The tools accepts local files or URL, so testers don't need local NetCDF 
files for trying. The email at [2] gives a complete example with a URL 
from GeoAPI JUnit tests.

  * If the "--format XML" option is omitted, then the metadata are shown
    in a plain text, non-standard, format. Remainder: this "plain text"
    format make extensive use of unicode symbols, so testers may need to
    try the "--encoding" option if the output doesn't seem right.
  * If the "--format XML" option is provided, then the metadata shall be
    in an ISO 19139 compliant document.


It is now time to start collecting errors, inaccuracy or elements in 
need of completion from users feedbacks :-).

     Martin
