Remove all MemoryModel-related code, since we're unlikely to use it again. Also changes some sample code to use a random generic name ("PruningAlgorithm") instead of MemoryModel in hopes that no one will be confused.

This does not remove IdleTimer, even though it now has no users.  I do plan to remove it, but I want to do that in a separate commit so it's easy to reference and revert if at some later point we want this functionality.
