Codegen adds redundant relations to the database model
------------------------------------------------------

                 Key: EMPIREDB-114
                 URL: https://issues.apache.org/jira/browse/EMPIREDB-114
             Project: Empire-DB
          Issue Type: Bug
          Components: CodeGenerator
    Affects Versions: empire-db-2.2.0-incubating
            Reporter: Matt DeHoust


Under some circumstances CodeGen produces redundant relations on the DBDatabase, which may
lead to problems if you use the empire-db model to create your schema. The script will fail
when you try to create the same foreign key relationship twice.

Steps to reproduce:
1. Define a schema with at least two different tables with foreign key relationships.
2. Use the "dbTablePattern" configuration option.
3. The generated DBDatabase will add the same relations more than once.

This is a major problem if you use empire-db to generate schemas with foreign key relationships.
If not, you can work around the problem by modifying the Database.vm template to exclude the
relations setup..
