Added byteToByte() and updated readme

Added a function called byteToByte() which generates bf code that sets
the value of one byte equal to that of another (both specified).
Might add specialist functions later, like tempToInput(), that use
predetermined byte values.

Also updated the readme with contact info.

Also also, you may notice some more new commented code in fitCodeGen.
That was going to be a function that returned a temporary byte that
wasn't currently in use, but... I dunno, maybe it was late or something,
but my brain basically fried. That was a heavy day.

ALSO also also, there's a new string generator, increase(), that
generates a string of pluses or minuses according to a certain value. I
did that because I thought I might need it, but didn't.
It might be worth making one function that you pass a single character
to and it lays it out nicely a specified number of times... might do
that.

Whooooof. That's a hefty description.
