Just enter the text you want to tokenize, press enter, and it should show up.
Super inefficient BPE tokenizer. But it's cool I guess. I made this a while before I published this, but I don't think you need the LMS or MMS thing for the actual tokenizer. The LMS is a list management system where you can actually create new lists using code (which you can't do with Scratch now) and a few other things. The MMS is the matrix management system which I think supports basic matrix operations... I believe it also allows tensors of n dimensions, but I could be wrong. I don't know if the MMS actually works fully right now.
