BUFFON - Master process:
  C++ version

  An MPI example program to estimate PI
  using the Buffon-Laplace needle experiment.
  On a grid of cells of  width A and height B,
  a needle of length L is dropped at random.
  We count the number of times it crosses
  at least one grid line, and use this to estimate 
  the value of PI.

  The number of processes is 8

  Cell width A =    1
  Cell height B =   1
  Needle length L = 1
