    GridFS Storage backend for Django.
    Based on https://github.com/django-nonrel/mongodb-engine/blob/master/django_mongodb_engine/storage.py

    This backend aims to add a GridFS storage to upload files to
    using Django's file fields.

    For performance, the file hierarchy is represented as a tree of
    MongoDB sub-collections.

    (One could use a flat list, but to list a directory '/this/path/'
    we would have to execute a search over the whole collection and
    then filter the results to exclude those not starting by
    '/this/path' using that model.)

    :param location:
       (optional) Name of the top-level node that holds the files. This
       value of `location` is prepended to all file paths, so it works
       like the `location` setting for Django's built-in
       :class:`~django.core.files.storage.FileSystemStorage`.
    :param collection:
        Name of the collection the file tree shall be stored in.
        Defaults to 'storage'.
    :param database:
        Alias of the Django database to use. Defaults to 'default' (the
        default Django database).
    :param base_url:
        URL that serves the files in GridFS (for instance, through
        nginx-gridfs).
        Defaults to None (file not accessible through a URL).
