This is in response to a related forum topic and allows the 10gen driver to be used alongside Mongoid 3.

This should be especially useful in our attempt to keep gridfs support in carrierwave-mongoid – at least until a moped-gridfs implementation surfaces (see jnicklas/carrierwave-mongoidMONGOID-32).

All references to ::BSON in the core lib and core rdoc were also changed to reference Moped::BSON instead, and this will need to be standardized in the core Mongoid lib to avoid regression.

EDIT: This was changed to remove the ::BSON alias altogether.
