#9684: Add a multidimensional counting_range

     Type:  Patches                          |     Status:  new
Milestone:  To Be Determined                 |  Component:  range
  Version:  Boost 1.55.0                     |   Severity:  Not Applicable
 Keywords:  multidimensional counting_range  |
---------------------------------------------+----------------------------
 I think a multidimensional (floating point) counting_range with
 configurable step size would be useful, at least I have found a need for
 that many times. Here is a suggestion, could something like this
 eventually be included in boost? What modifications should I make (after
 switching to boost::bind)? The iterated values are evenly spaced from each
 other and the boundaries.

 Example usage:

 boost::array<double, 2> start{-4, 3}, end{4, 11};

 const size_t samples_per_dim = 2;

 for (const auto& i: volume_iterator(start, end, samples_per_dim)) {

   print(i);

 }


 Output:

 -2 5

 2 5

 -2 9

 2 9
