    Marcin Skladaniec updated CAY-794:
    ----------------------------------

        Attachment: abstract-obj-entity.diff

    After a consultation with Andrus another small update to the patch: the attribute is stored in XML as "abstract" rather than "isAbstract" to archive constant naming pattern

    > 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.
