Detailed Description

Mapping from DebugVariable to/from a unique identifying number.

Each DebugVariable consists of three pointers, and after a small amount of work to identify overlapping fragments of variables we mostly only use DebugVariables as identities of variables. It's much more compile-time efficient to use an ID number instead, which this class provides.
