Fixed lots of bugs, added much more sane and efficient ParseAction table instead of recalculating every time. Fixed lots of bugs and inefficencies. Some temporary hacks in the table, mostly having to do with not having an EOF Symbol yet.

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.

Actually parses LR(0) grammers and sentences\! Only two problems is very inefficint gotoTable() and actionTable(), and it REJECTS the sentence after completing the Goal->Sentence(*) production. However, need to go to bed now. Does practially work though\! Yay\!
