All object witch is persistent, extends Persistent abstract class. Each object has its own UUID identification, which is useful.
For coordinates<?> from JScience, persistent wrapper was created.
I tested Point, all Curves and multi-point for checking of right count of object in database after operations with these geometries.
I have started implement utils classes for web environment - Change merger witch should be useful for user (is not implemented all).
