Fixed my nextByte and nextTwoBytes to take in the CPU's PC as a parameter instead.  Hopefully this will fix the CPU's PC being NaN at that point.
Working on my cpu again.  Testing each opcode.  Lots of them work, but right now I'm trying to get compareToX to work.
Looks like I fixed compareToX now.  On to branch or something!
MOM GET THE CAMERA.  12DONE WORKS.  LOOK MOM I DID IT.  Okay time to make sure all the example programs work but right now I'm pushing so Alan can see what I diiiiiiid.  SO MUCH HAPPY.
