I wouldn't mind if we add methods for ClassDescriptor lookups to the  
DataObjectUtils. BTW PersistentObject defines 'getObjEntity' method.  
I'd say we replace that with 'getClassDescriptor' and move it to a  
utility class.

While we are at it, maybe rename DataObjectUtils to something more  
appropriate and shorter. CayenneUtil? Cayenne? ("Util" is already  
taken, and I'd rather it identify the origin of the framework).

I sort of like calling it just "Cayenne" (for the same reasons of user  
simplicity), but then it implies this is a central class in the  
framework, and has more than just lookup-by-pk or give-me-metadata
