iso geometry integration

Check out the bottom of ISO Geometry Research for the details ...

1. Add a converter from ISO Geometry classes to Java Shape
   (and then stand back and watch renderer do its magic)

2. Review the spatial function code and make sure it delegates to the ISO Geometry class as needed

3. Set up a GeometryFactoryinterface

   • JTSGeometryFactory will produce JTS Geometry objects
   • ISOGeometryFactory will produce ISO Geometry objects

4. (Note specific datastores may wrap the provided GeometryFactory in order to make good on their restrictions; letting client code know
   the GeometryFactory that works for the DataStore is a similar problem to adverising FilterCapabilities)
