Propagate best instead of current solutions in parallel tempering? #33

Currently, two neighbouring replicas exchange their current solutions. It may be better to propagate the best found solutions to the coolest replicas to achieve early convergence.

We should think this through very thoroughly and carefully validate the envisioned improvement. For now I will leave the swapping mechanism as is since it has shown to work in various applications.
