Implementation of a multi-key dictionary, i.e.: (key1[,key2, ..]) => value

This dictionary has a similar interface to the standard dictionary, but is extended to support multiple keys referring to the same element.

Multi-key dict provides also extended interface for iterating over items and keys (e.g. by the key type), which might be useful when creating, e.g. dictionaries with index-name key pair allowing to iterate over items using either: names or indexes. It can be useful for many other similar use-cases, and there is no limit to the number of keys used to map to the value.

There are few other useful methods, e.g. to iterate over dictionary (by/using) selected key type, finding other keys mapping to the same value etc.

This package contains the Python 3.x module.
