Detailed Description

A class to uniformly access the prototype of any Object and walk its prototype chain.

The PrototypeIterator can either start at the prototype (default), or include the receiver itself. If a PrototypeIterator is constructed for a Map, it will always start at the prototype.

The PrototypeIterator can either run to the null_value(), the first non-hidden prototype, or a given object.
