Two additional options in the project settings.py
file are allowed:
   * namespaceurlmap : allows configuration for namespaces to map to names
other than that url itself in the url that gets generated.
URLs are generated by the namespaces in the urls.py file. This level of indirection
allows urls to be generated freely from the url.
   * params_required_for : explicitly declare which url tokens will receive parameters.
prevents a parameter being required for each `/` in the url.
