first commit
stable, now with unit tests and headers
still trying to get List to work
very stable now.  list working.  argument lists working.
improved error handling and reporting.
implemented logging.  added test cases for it.
fixed a terrible bug in build.xml "build/build" vs. "build/classes"w
got rid of "<" because I got rid of inner "(" around arguments
 (which I suspect started working because I got rid of 'unused' code in
  Instancer.g) ... but anyway, now the language is back to what I wanted
fixed build.xml to conditionally compile Instancer.g
