Dead code removal.
Some small-ish refactoring to prepare for a more comprehensive refactoring later.
Split the 'parserTables' function into multiple smaller functions (one per table) and encapsulated them in a module.
Removed unused parameters from some of the ParserTables functions.
More refactoring of the ParserTables module.
Moved the parserTypes function into a new ParserTypes module, and renamed the function to 'emit'. Later, we'll split it up into smaller functions.
Implemented a Count property on LrParserConflictSet and LrParserActionSet.
A bit more refactoring, and added some OPTIMIZE comments for later.
