H2GIS workspace

[ebocher]

Since H2GIS is in GeoTools (geotools/geotools#4043) we can expose H2GIS in GeoScript.

This looks great! Thanks for the PR! Eventually, we should add a H2GIS section to https://jericks.github.io/geoscript-groovy-cookbook/

Any idea why the build can't find org.geotools.jdbc:gt-jdbc-h2gis:jar:29-SNAPSHOT?

Error: Failed to execute goal on project geoscript-groovy: Could not resolve dependencies for project org.geoscript:geoscript-groovy:jar:1.21.0-SNAPSHOT: Could not find artifact org.geotools.jdbc:gt-jdbc-h2gis:jar:29-SNAPSHOT in osgeo-snapshots (https://repo.osgeo.org/repository/snapshot/) -> [Help 1]

I used a local compiled version. I don't known why the H2GIS extension is not published on https://repo.osgeo.org/repository/snapshot/
I will send a message to the list

Hi @jericks
The H2GIS workspace has been updated and it rocks now !
New methods are available on the H2GIS workspace to load, save, link file or table in a database.
Added also some unit tests
There is still a bug when I try to draw a linked shapefile. It seems related to the StreamingRenderer but the layer is correctly rendered. The test is currently disabled (drawLinkedShapeFile()).
Feel free to test and comments this PR

There are a couple of failing tests:

Hi @jericks

There is several conflicts due to the fact that some modules of GT use a very old version of H2 database : 1.1.119. H2GIS uses the 2.1.214.
As geoscript is not modularized, I don't see a solution to solve this issue.
H2GIS should be put in a specific container isolated from GT modules that use another version of h2.
Best regards
