Robert Griesemer 3cfd91f85b daily snapshot:
- 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
