Stores the mapping between callee and caller methods for a router.

This class is primarily used in a get_metadata_routing() of a router object when defining the mapping between a sub-object (a sub-estimator or a scorer) to the router’s methods. It stores a collection of Route namedtuples.

Iterating through an instance of this class will yield named MethodPair(callee, caller) tuples.

New in version 1.3.
