django_tokyo_persistent_store.py

""" Idea taken from here: http://github.com/ericflo/django-tokyo-sessions/tree/master
    Basically this is a thin wrapper around django's cache fremwork to allow for persistent
    keys with no expiration values.

    I'm using it to store unique values that get updated infrequently, ie via cron, and which
    don't need to expire, just be updatable.

    Requires TT_PERSISTENT_STORE to be set in settings.py using the memcached format.
