Manageable diff for ProjectQ-Framework consideration

[WrathfulSpatula]

The vm6502q organization intends to officially support Qrack as an optional simulator for ProjectQ, under the Apache 2.0 license. This lets Qrack take advantage of the compilation of ProjectQ. It also provides effective cluster/multiprocessor support for Qrack via a stack of SimulaQron -> ProjectQ -> Qrack.

In the process of developing and debugging the integration, the changes went out of the original scope, and the diff diverged too far from the official original project. The immediate priority is to revert the diff as much as possible and to break the changes up into decoupled PRs, if necessary, to present for consideration for adoption as an optional simulator in the official original ProjectQ repository.

Each issue should address as tight as I change as possible, starting with the cosmetic ones.

I will identify separate issues, starting with the cosmetic.

The diff was reverted as much as possible, and the branch was squashed.
