> Implement the possibility for an objEntity to be abstract. These means that the entity class generated by the template will be abstract.
> 1. Add atttribute isAbstract within <obj-entity ...> in the Cayenne data map.
> 2. Add checkbox to the modeler "[ ] abstract class"
> 3. void setIsAbstract(boolean) and boolean getIsAbstract() added to ObjEntity.
> 3. change template generation to add 'abstract' keyword
> Other changes (such as throwing runtime exception when querying abstract entity with no concrete subclasses) could probably wait until later since they need to be implemented as part of inheritance.
