Cache->expire is private

Cache->expire is private. Make it public for the love of God or add set&get methods.

Totally agree - this should be configurable in the admin too

Actually, at the moment cache library is useless for any complicated addon.
Cache->set() doesn't allow to create folders.
Cache->delete() doen't work with patterns.

I'm not pushing - it is your call. But Cache->expire should be public.
