NonEquilibrium switching protocol implementation

[ijpulidos]

These sets of changes are aimed towards a minimally functional implementation of a NonEquilibrium switching protocol, based on the objects and lessons learned from the NonEquilibrium cycling protocol.

Still a WORK IN PROGRESS, but this should be useful as a good first skeleton on what the protocol should look like.

Comments from a meeting with John:

I still like the idea of including [ eq + neq switch ] within a single block, since you can easily chain these together as much as you want or run as many in parallel as you want.
You end up with the same result.
