Detailed Description

Augments the PathHistory in the envelope with the other necessary information from the envelope.

These should be derived from an incoming message.

These objects can then be used for storing of information about a path outside of the incoming message's header.

These are used for: 1) information about the currently executing message 2) combining the maximum paths along a reduction 3) combining multiple paths in Charisma and SDAG programs

This can be constructed from an envelope.
