* Changes we've collected over the years to deal with hierarchical
@Entity classes.
* Bug fixes (mostly around cache stuff)
* Allow the conf to specify a UUID generator.
* Support for BeanMap, BeanSet and BeanList

* We added our own unit tests that pass, but some of EBean's don't pass.
All of our own application tests pass.  We need to consult with Rob on a
good way to make these changes mainstream (and allow us to fix the
broken tests.)  A more publicly-consumable release should be available
soon.
