simple brainfuck-to-C compiler.

this program compiles any brainfuck program into a C program!
it also automatically compiles the C program with GCC, with optional
optimization flags. (-O1, -O2 etc etc...).

the GNU C Compiler does
the heavy lifting here...

hanoi.bf is in the repo. to test it, run:
cargo run hanoi.bf -o hanoi -O4
you must have GCC installed in order for this code to work properly, obviously
