Persist and restore polymorphic classes
---------------------------------------

                 Key: ISIS-118
                 URL: https://issues.apache.org/jira/browse/ISIS-118
             Project: Isis
          Issue Type: Bug
          Components: Runtimes: Dflt: Objectstores: SQL
    Affects Versions: 0.1.2-incubating
            Reporter: Kevin Meyer
            Assignee: Kevin Meyer


Currently, the SQL OS does not persist properties of super-classes when a polymorphic class
is persisted. Additionally, abstract classes and interfaces are treated the same as concrete
classes.
There are two obvious options:
1) The persisted polymorphic class creates a row in an uber-table of concatenated properties
of all super-classes.
2) The persisted polymorphic class creates rows in each table that corresponds to a super-class
(the concrete sub-class is contained in multiple tables, 1 per super-class).
