FINALLY fixed an error that took weeks. Turned out that the ParseRule was shallow copied, and the lookahead was not copied correctly. So it got extended and thus skipped over the state when it should have been redone.

Started adding the nullable parts machinery. Also started to fix addStates for RNGLR and null reductions so it only truncated the rule to what had already been parsed, but now it looks like it maybe shouldn't truncate at all and use pointer position for length. However, I have to go to bed and will pick up later.

The out of orderness was actually the fault of the dot graphing program, not Kraken, so that's good news. DOT generation has also been modified so that it properly inserts \n's (actually \n's) where line returns are so that dot can parse the \n and not the line return.

Cleaned up some debug messages, parseInput(string) now returns a parse tree of NodeTree*. This is done by having each non-terminal Symbol have it's own subtree and calling a method to combine subtrees and terminals on each reduce. The output is now the DOT version of the parse tree.
