DESCRIPTION
-----------
  mongoid_grid_fs is pure mongoid 3  / moped implementation of the mongodb
  grid_fs specification

   ref: http://www.mongodb.org/display/DOCS/GridFS+Specification

   it has the following features:

    - implementation is on top of mongoid for portability.  moped (the drive)
      is barely used

    - simple, REST-like api

    - support for custom namespaces (fs.files vs. image.files)

    - pathnames and io-like objects can be written to the grid

    - auto-unique pathnames are generated (by default) to avoid collisions using #put

        'path/info/a.rb' -> '$object_id/a.rb'

    - #[] and #[]= methods which allow the grid to be used like a giant file
      hash in the sky

    - supprt for data_uris
