- use explicit expression lists instead of binary trees to represent lists of the form a, b, c
(per discussion w/ Russ)
- use explicit nodes for various language constructs for better readability
- various adjustments in parsing and printing

next steps:
- clean up AST fully so it can be checked in as library

for pretty printer purposes - now properly ignored as white space since we
have line/col information)
- changed sample use in comment to an actually compiled function to make sure
sample is actually working
- added extra tests (checking line and column values, and the tokenize function)

if T has pointer methods.  this is just a heuristic
but it catches the problem robert ran into and
lets me put the larger interface issues aside for
now.  found one bug in pretty.
