It looks very good!
Quick review of the docs structure:

No need for core/ subdirectory, just move the files one level up, and remove the directory. The name core is an informal one, that, there is no physical structure named core.
The `extension/' directory does make sense, please keep it.
Please, remove _a_ infix and _it suffix from file names. Simple names like create.rst, fill.rst, subhistogram.rst are clear enough.

Nitpick: The file name cumulativehistogram.rst should read cumulative.rst. It already lives in histogram/ directory.

@codejaeger Well done! It's great to see GSoC features covered with documentation :-) I'm happy to approve this PR. No objections from you @lpranam ?

I have offered a few comments, but those are not show-stoppers.
Technical writing is not a trivial activity. We can always improve and refine documentation in future.

I'd suggest we merge it after we merge PR #499.
Next time you may prefer to stick docs in the same PR as implementation and tests.

doc/histogram/cumulative.rst

I do not like the idea of storing 7MB files in GIL's repo.
Unfortunately, I can not offer an ideal alternative yet.

I'd suggest a temporary solution:

Remove the images from this PR

Paste the images as comments to this PR

Replace filename with URLs from GitHub

.. figure:: https://user-images.githubusercontent.com/12345/12811123-3877a980-8375-11ea-9960-1b88a3f9f87b.png ...

The thing is, once we start adding big binary files to Git repo, then even if we find an optimal solution for hosting images for docs, we will not be able to get rid of them easily, from Git history.

I have (slowly) started collecting externally hosted test images in dedicated repo https://github.com/boost-gil/test-images, so I perhaps we could have examples/ folder there and link from docs to there.

What do you think @lpranam ?

In my opinion, in docs we don't have to use the full-size images. Docs just need to demonstrate what our algorithms can do and do not need to show the exact accurate images, we can use highly compressed and small resolution images in docs. Otherwise what @mloskot suggested the great. I have no other objections regarding this PR.

@codejaeger Well done! It's great to see GSoC features covered with documentation :-) I'm happy to approve this PR.

Thanks a lot @mloskot : )

I'd suggest we merge it after we merge PR #499.

Yes sure. Also this PR contains docs for the algorithm histogram equalization. I haven't pushed it yet since the histogram class is a dependency for it. Should I remove the docs for the algorithm?

I have compressed the images, they now occupy about 34 KB and 24 KB. I can also do what @mloskot suggested if needed.

though it is compressed for doc would be great to add real one on that repo so we can have those images for later.

@codejaeger If you want to try the idea outlined earlier, you should have now the write access to https://github.com/boost-gil/test-images Feel free to create doc/ directory (and any necessary subfolders) and put your images in there.

@codejaeger Could you add full size/resolution images to the test-images repo as @lpranam suggested?

@codejaeger Ping ☝️

Yep doing it. Thanks for the reminder, sorry I had totally forgotten about it.
