Detailed Description

An in-memory implementation of the Scope interface.

This can act as a stand-alone Scope object or serve as an in-memory cache for another implementation. This implements a nametree, which is a a set of Symbol objects (the set owns the Symbol objects). It also implements a maptable, which is a list of rangemaps that own the SymbolEntry objects.
