1 - Compile and Run a Single Reason File
OCaml's compiler has a nice, flexible pre-processing step described in
run.sh. A Reason file is just an ordinary OCaml file that leverages that feature. Therefore, everything that semantically works in OCaml should, in theory, work in Reason, and vice-versa.
We start with a shell file,
run.sh, which, upon execution, compiles & runs the output.
