Standardize IdMap and IdMapEntry

[hcook]

Requests for information about the meaning and properties of certain ids used in diplomatic protocols to be stored in the Object Model necessitates having a common representation of id spaces across protocols. I refactored some common code related to displaying this information during elaboration such that an underlying abstract class and trait are now shared across the representations.

Type of change: refactoring

Impact: API addition (no impact on existing code)

Development Phase: implementation
