router
------
We use a router class for mapping URLs to code. This section controls
how that router works.
cache: whether to cache the router in memcache (or another caching
mechanism). Defaults to true, but may be set to false for
developers (who might be actively adding pages, so won't want the
router cached) or others who see strange behavior. You're unlikely
to need this unless you're a developer.
