merged exp.FSM into master, but did not yet remove clutter

I merged exp.FSM with master locally, manually fixing conflicts (none serious,) and pushed to WilCrofter/swirlfancy/master.

I've left the clutter in place here are the files which I think we don't need:

> R/ansTests.R
> R/control.R
> R/simpleFSM.R
> R/states.R
> R/utils.R
> inst/testMod.csv
