// Based on code by Makoto Matsumoto, Takuji Nishimura, and Shawn Cokus
// Richard J. Wagner v1.0 15 May 2003 rjwagner at writeme.com
the random seed for the Mersenne-Twister is provided by our R-function
which gives an (random) integer to the C++ function srand() which in
turn sets the seed in the code.
Using the set.seed in R makes now the results reproducible,...
