- library/mongo: * updated interface to current nx * updated to mongo-c-driver 0.4 (current version) * The mongo c-driver does not allow to add DBRefs, since it refuses to accept field names with leading '$'. So we skip these tests for the time being.
- nx::mongo: * implemented type "reference" similar to "embedded" * all referenced objects are for the time being auto-dereferenced * new method "show" for mongo mapped classes * added two new example files example-nx-reference-many.tcl and example-nx-reference-one.tcl
