  Contract: main: void -> int

  Purpose: ask the user for Scoville ratings and give
           him/her the minimum recommended audience for
	   each, printed to the screen,
	   until he/she enters a negative rating
	   to say he/she is ready to quit -- and then
           it prints to the screen the number of
	   ratings given by the user, and the highest
           of Scoville rating given
  
  Examples: if, when I run this program, I enter:
            250, 750, 1250, 500, 1000, -2 when prompted, the following
            would be printed to the screen:
the minimum rec'd level is: infant
the minimum rec'd level is: toddler
the minimum rec'd level is: adult
the minimum rec'd level is: toddler
the minimum rec'd level is: adult

Number of Scoville ratings given: 5
Highest Scoville rating given:    1250
Number at the toddler level:      2
----------------
            if, when I run this program, I enter:
            -3 when prompted, the following should be printed
            to the screen:
Number of Scoville ratings given: 0
Highest Scoville rating given:    not applicable
Number at the toddler level:      0
