Subject: [boost] [histogram] Working with standard algorithms

I would like to see a better integration between boost.histogram and
standard algorithms, especially those from <numeric>. Today they do not
work together because the dereference operator of the axis iterator
returns a pair (index and content) rather than the content.
An example of where standard algorithms could be useful is calculating
the cumulative distribution of a one-dimensional histogram, which ought
to be a simple as:
auto& axis = h.axis();
std:partial_sum(axis.begin(), axis.end(), axis.begin());
Another example is ranking a set of histograms based on the cosine
similarity  using std::inner_product().
