It works again! and more!

About to change a few things:
 - symbols and errors will have a range not a position
 - remove view/output token type, those should just be View and Output
   structs
 - Figure out some formatting stuff? (add a dep? I dunno)
 - Move to non-quoted dot-delimeted variable references.
 - Add loops.
 - Add conditionals?
 - Add more!
