Move definition of REFERENCE classes to its own file

Dereferencing is still defined in high-level.lisp, this might change
in the future since I'm sort of restructuring a little bit.

Slight syntax adjustment
...
I just couldn't stand "dotimes x 200", and "for x do 200 times" just
feels so much nicer. I also added a space after an opening parenthesis
to ensure that my tokenizer gets to eat this particular type of
unnecessary but permitted whitespace.

That revert before? I was kidding, I concede nothing! I win! (i.e. we
talked for a while and both decided that an argument vector was better
after all)
