That said it will clean up our code a lot - we can finally edit a 
Geometry in place without being forced to create a new one, and so on.

Andrea and I have a couple of ideas on how to speed up GeometryFilterImpl:
- Andrea would like to hold a cache in memory
- I would like to try a spatial index, such as IndexedShapefile
