Description: expiringdict
------------
expiringdict is a Python caching library. The core of the library is ExpiringDict class which
is an ordered dictionary with auto-expiring values for caching purposes. Expiration happens on
any access, object is locked during cleanup from expired values. ExpiringDict can not store
more than `max_len` elements - the oldest will be deleted.
**Note:** Iteration over dict and also keys() do not remove expired values!
