Proposed change for issue #33

- Limits the depth of a dump, so dumping an ORM entity with lots of relations won't result in dozens of layers and cause heap memory errors.
- Allows the developer to specify a depth at the init and notify level and if nothing has been specified it retains the CF default of 9999 levels.
