Detailed Description

This range class represents a range of random numbers.

It is categoried as a Notional Range

It could be used as follows

      // Create a range of 10 values, whose value are between -100 and +100
      stlsoft::random_range   r(10, -100, +100);
   
      // Dump them to stdout
      stlsoft::r_copy(r, std::ostream_iterator<int>(" "));
