* Add a route (note - this doc is not currently in sync with the code, need to update)

* Director::addRules(50, array('admin/mymodel/$Class/$Action/$ID' => 'MyModelAdmin'));

*
* @todo saving logic (should mostly use Form->saveInto() and iterate over relations)
* @todo ajax form loading and saving
* @todo ajax result display
* @todo relation formfield scaffolding (one tab per relation) - relations don't have DBField sublclasses, we do
* we define the scaffold defaults. can be ComplexTableField instances for a start.
* @todo has_many/many_many relation autocomplete field (HasManyComplexTableField doesn't work well with larger datasets)

* Long term TODOs:
* @todo Hook into RESTful interface on DataObjects (yet to be developed)
* @todo Permission control via datamodel and Form class
