Barbarshop program as a producer/consumer using a circular
buffer, semaphores and shared memory.  Three arguments 
control the program:
  1.  How long in Seconds Consumer process should sleep before
      starting - default = 1 second.

  2.  Used to determine if Barber Shop contents are to be printed:
      default =0, not print.

  3.  How long Producer should sleep between each search of the
      wait area - default = 3.

NOTE: Person in the chair with the lowest number is the Next Person
      of that category to have their hair cut.

NOTE: How position numbers change as someone's hair is cut, i.e., in X,
      the next NC is 18, in X+1, the next NC is 17 (guy in 18 moved to
      the barber chair.
