Resolved issue with Logger (caused by adding multiple FileHandlers to same Logger)
Fixed naming conventions for output files to create toy.log, toy.tables using toy.grammar, which was prev. toy.cfg.txt (removed all .txt extensions)
Fixed issues where equivalent sets of terminal symbols, production rules, and production rule instances were not seen as equal or not returning the same hashCode() value

Tables are now produced correctly. Ready to continue on to TableCompactor, which will take in the created tables and return simple arrays which can be serialized as efficiently as possible. Also need to implement Conflict notifications.
