- Deleting memoized functions now properly functions in production
environments where multiple instances of the application are running.
- get_memoized_names and get_memoized_keys have been removed.
- Added ``make_name`` to memoize, make_name is an optional callable that can be passed
to memoize to modify the cache_key that gets generated.
- Added ``unless`` to memoize, this is the same as the unless parameter in ``cached``
- memoization now converts all kwargs to positional arguments, this is so that
when a function is called multiple ways, it would evaluate to the same cache_key
