- add -I support to dbicdump
- Relationships
- - Re-scan relations/tables after initial relation setup to find
- ->many_to_many() relations to be set up
- While scanning for many-to-many, scan for implied rels as well (if
foo->belongs_to('bar') and baz->belongs_to('bar'), does that impliy
foo->might_have('baz') and the reverse?)
