/*
    READ

    read.c handles input. It doesn't do anything terribly interesting
    or exotic. Input is taken from fgets. If the input is a user
    command, then command is executed. Otherwise, the input (presumed
    to be Lisp code) is passed to the functions in parse.c.

/*
    TODO:
        -- make it so that newlines don't have to be
            added to every input string (problem
            with tokenize in parse.c?s)
        -- reader macros
