# Craps Simulator
# Prints the value of two dice and their total for the number
#  of throws specified by "n" unless the user craps out.
#
#  Test Change to push
#
# Variables Used:
#    n:       Number of times to throw the dice.
#    i:       Counter variable within "while" loop to count the number
#             of time the dice were thrown with 'n' being the max.
#             If a 'natural' (see below) is thrown, the rest of the
#             loop is skipped so the throw doesn't count.
#    throw_1: Value of the first die thrown.
#    throw_2: Value of the second die thrown.
#    total:   The sum of the two throws. (throw_1 + throw_2)
#    header:  A pre-defined header literal.
#    result:  Based on the special conditions, = one of several
#             possible strings. (win, loose, doubles, etc.)
#    point:   Stores the value of the current "point" that the player
#             needs to roll in order to win.
#
#             Point is also used as an end-of-game switch. "1 = end"
#             if the point was made, 7 was thrown, or the set number
#             of throws was exhausted. Each of these conditions will
#             cause the game to end.
#
