-  This program test the random function
-  It gets 10M random values
-  that are placed in 10000 windows
-  and print the number of occurence for each window
-  and the profile of the distribution
-  of the counts
-
-  - this gave very bad value due to a modulo problem
-    but after this solved
-    it still shows strange wings !!
