Also rudimentary code generation. The difficulty
is that for Haskell generation, we need to know
whether an expression is a string or in to send it
to standard output. So we will need to begin

Also adds parenthesization of fostr expressions.
Recasts code generation in terms of bottomup processing
of a local strategy.
