RandPN:

--------------------------------------------------------------------------
   Generate a Poission random matrix using a normal approximation.
   lambda should be >= 5 for this to work.

   This routine forces the results to be positive since the Poisson 
   distribution is always > 0.

   Type RandPN for a demo.

--------------------------------------------------------------------------
   Form:
   q = RandPN( lambda, n, m )
