Equivalence Classes for Agents

[cameronmore]

To be addressed in release 2.0 is the issue of axioms for classes such as Enemy Organization (per issue #431 ) , Organization Member (per #422 ), and existing terms such as Allied Person and Neutral Person. The question is, since the associated roles can be born by any agent (person or organization), do we need equivalence classes for all the persons and agents for the different roles.
