MP8 has you implement a lexer for MicroML. Keep in mind that your solution must define every required function,
otherwise the grading program will not compile and you will receive no points for the entire homework set.
For example, if you decide not to implement the function splat (for whatever reason), you need to have it defined as:
let splat x = raise (Failure("Whatever you would like"))
IMPORTANT: Make sure that you read the README file in the grader
bundle . This file
contains important information.
Also, make sure you read the "Guide for Doing MPs".
