# purpose: to ask the user for the ticket price range
#          and price increment, and then print to
#          the screen the profits for all prices
#          in that range inclusive in the form of
#          a simple table.
# example: not really applicable; this simply
#          asks the user for ticket price range and
#          increment, and 
#          prints the profits for these ticket
#          prices to the screen
