This is turning out to be a bigger reorg than expected..hoping
to have it straightened out today.

In short, I'm working towards having a cleaner separation between
code that implements the UI(s) and the actual interpreter. Need to
do this in order to non-hackily support .NET code calling back
into Haskell. The added modularity will, I hope, be deemed a
worthwhile change.
