Fixed a lot of bugs. Actually gets through the entire experimental grammer. (A largeish experimental grammer for Kraken written to continue testing and to really start language development.

Lexer/RegExs now work on a very basic level. Regular expressions have not been fully implemented, but the structure is there. It creates trivial regexs that only accept a specified sequence, no actual regular expression power.

NodeTree now also has a link to the Symbol it represents.

Changed followset to work on states, fixed many bugs. Kraken now should have a fairly legitimate LALR(1) parser. (null productions have not yet been added.)

Added a firstSet(Symbol*) function that takes in a Symbol* and returns a vector of Symbol* s that are the first set of the first Symbol*.

Added EOF symbol, making the getTable() saner for ACCEPT and lookahead support in ParseRule

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\!

Changed from iterators, which become invalidated if vector is changed, to classic indexing. Now runs! However, the results are incorrect. Closure seems to work through.

Added first go at creating stateSets. This is a commit to save work, as it still segfaults.:

First work on Kraken! Basic node tree system re-written from WTS-Language, can output .gv files of the node tree.
