The background on the above is that when Greg looked at my min_rand
class, he commented that it was very close to being useful as an STL
compliant input iterator.

I tried to work that out, but got hung up on termination.  For
example, if you wanted 1000 random numbers in a vector, you could
write something like:

   min_rand rng;
   vector<long> vec( rng, ??? );  // oops! no way to specify end
               
A third container-like class is needed, I think.  end() would return
0,
begin() would return an iterator with operator++() which returned
++rng for 1000 calls, then returned 0:

   min_rand rng;
   iter_counter itrc( rng, 1000 );
   vector<long> vec( itrc.begin(), itrc.end() );

Anyhow, that is the problem Greg is thinking about.
