compute fep and fix wall/reflect

The compute fep acts on the pair interactions that are specified, so the wall/reflect should not have a *direct* effect on the free energies. (That being said, if the volume option is used, then the total volume of the box is considered when correcting for volume fluctuations.)
However, I suppose the confinement will have an effect on the calculated free energies depending on your system, not related to how the compute fep works.


Thank you so much for your replies.
