- implemented elastic tabstops algorithm, now correct and documented
- first cut at printing comments (use -comments flag, disabled for now)
- struct field types are now aligned (using elastic tab stops)
- needs more fine-tuning

* fixed a bug in test script
* added quick smoke test to makefile and invoke it in run.bash
  instead of the full test
