 Contract: grade_msg : char -> string
 Purpose: 
   expects a char corresponding to a letter grade,
   and produces the appropriate string for that grade,
   according to the following:

    'A' or 'B' ---> "High pass"
    'C' or 'D' ---> "Pass"
    'F' or 'I' ---> "Try again"
    anything else ---> "Huh?"

 Examples: 
    grade_msg('A') == "High pass"
    grade_msg('D') == "Pass"
    grade_msg('F') == "Try again"
    grade_msg('Q') == "Huh?"
