The 'prog' parser now parses many top-level forms, and some exprs. I'm
making liberal use of the "tt punt"; that is, if a form has a { ... }
in it, I just parse that as braces surrounding a bunch of tts.

The test-driver is now defaulting to parsing as progs.
fix to number parsing
got the binop hierarchy in there
add clean rule
start to abstract test-driver over prog- and tt-based-parsing
many (most?) files now parsing, with big tt-based caveats
working
bit spec on floats is optional
