Initial commit
`Tokenizer` can _just barely_ parse a basic, well-formed move list. Initially, I wanted to provide the movetext as a `Stream` rather than a string, the idea being that it could be processed as it was being read from a file without having to read the entire file into memory first. I had difficulties with the stream being unreadable in `Tokenizer.ParseMoves()`, so I switched to a string in order to get the actual parsing logic down first. Because of the `yield return` strategy, the debug console output includes all of the expected halfmoves multiple times in various orders. After running a test, generally the full, in-order list seems to exist at the bottom of the output.
