- Implemented support for the `set` instruction in the

  assembler.

  The main thing I had to do was implement the parsing
  of the condition code token, but that wasn't hard to
  do, since I had already done the lexing part already.

  The next thing to do, will be to design a calling
  convention for Sux.
