###BF interpreter
#####notes
- memory expands indefinitely in both directions
- cell size is one byte
- to send input to a program, pipe it in. E.g. echo "racecar" | ./homerow reverse.bf
- input instruction zeroes the byte under the pointer on EOF
- this is not a reasonable approach to this problem; I just wanted to mess around with Parsec
#####To run hello_world.bf
git clone git@github.com:ckw/homerow.git
cd homerow
ghc --make homerow.hs
./homerow hello_world.bf
