  Signature: main: void -> int

  Purpose: prompts the user for Scoville ratings of chilis,
           and for each it prints to the screen the appopriate
           minimum-age audience for a chili of that spiciness;
           it ends when the user enters a negative Scoville
           rating
  
  Examples: if, when you run this program, you enter, when prompted,
2
30000
250 
500
750
1000
-7
           ...then it will print the following to the screen
              between the prompts:
the minimum-age audience for such a chili is: infant
the minimum-age audience for such a chili is: adult
the minimum-age audience for such a chili is: infant
the minimum-age audience for such a chili is: toddler
the minimum-age audience for such a chili is: toddler
the minimum-age audience for such a chili is: adult

pseudocode:
ask the user for a chili rating

while the rating is >= 0
    determine and print out the minimum audience for that rating

    ask the user for the next chili rating
