Detailed Description

Transparently reference and de-reference already saved embedded objects.

This manipulator should probably only be used when the NamespaceInjector is
also being used, otherwise it doesn't make too much sense - documents can
only be auto-referenced if they have an *_ns* field.

NOTE: this will behave poorly if you have a circular reference.

TODO: this only works for documents that are in the same database. To fix
this we'll need to add a DatabaseInjector that adds *_db* and then make
use of the optional *database* support for DBRefs.
