Default settings
================


All default setting must be set in a module called 'settings' inside the
application. Application's ``__init__.py`` must contain the lines::

  from jmb.core.conf import inject_app_defaults

  inject_app_defaults(__name__)


So that all variables (*UPPER CASE ONLY*) get copied to settings singleton.

NOTE: in order to make this all work the module must not have been imported
      before the settings module. This means we should put ``tsettings`` out
      of the module to be sure it will work for applications
