/*!
    This file contains code to convert unsigned integers to strings
    at compile-time, and then modify those strings include more
    information.
    
    One use case is to convert library MAJOR, MINOR, and PATCH
    numbers into a custom string (see below).
    
    Other types like signed integers and floats can be added
    with template specializition on the converter struct.
