Description

Apart from the default class supplied by Boost.GIL, there are also provisions to use external containers like from std::vector, std::map, boost::histogram etc. These are provided as extensions.

Extensions

Currently the following are available:

1. std::vector (1D histogram support)

2. std::map (1D histogram support)

3. std::array (1D histogram support)

4. std::unordered_map (1D histogram support)

5. boost::histogram

Adding an external container

The workflow should be:

1. Provide overloads for fill_histogram(must), make_histogram(optional) etc. in a new file preferably named after the container type in extensions/histogram/.

2. Add tests to test/extensions/histogram.

3. Add docs to docs/histogram/extensions.

4. Other cmake, Jamfile, config etc. file changes.
