 Signature: describe_grade : char -> string
 Purpose: expects a grade expressed as a char,
          and produces a string description for that grade.
          If an unrecognized grade is given,
          it produces the string description "Unrecognized Grade"

 Examples: describe_grade('A') == "Excellent"
           describe_grade('b') == "Very Good"
           describe_grade('C') == "Acceptable"
           describe_grade('d') == "Marginal"
           describe_grade('F') == "Insufficient"
           describe_grade('g') == "Unrecognized Grade"
