The concept of "temporary resource" has its own extension-point; looks like
you can add a placeholder for an in memory grid coverage; right now I just
see a single implementation for turning a FeatureType into a temporary
MemoryDataStore.
What would a good descriptor be in this case? Probably a GridCoverage2D (I
think that is the in memory implementation of grid coverage is it not).

Cheers,
Jody
