Group include directives, sort within group:
* In headers of GIL core and extensions:
1. boost/gil/extension/*
2. boost/gil/*
3. boost/*
4. C++ standard library headers
* In programs:
1. boost/gil/*
2. boost/*
3. C++ standard library headers
4. "xxx.hpp" for local headers
Add basic guidelines to CONTRIBUTING.md.
Add/Remove #include <boost/config.hpp> or std headers un/necessary.
Rename gil_concept.hpp to concepts.hpp.
Remove gil_all.hpp - we already have all-in-one boost/gil.hpp.
Tidy up and unify copyright and license header.
Tidy up formatting and excessive whitespaces in some comments.
Remove Doxygen block with file description, author, date, etc.
Remove dead or commented pragmas and directives.
Trim trailing whitespaces.
The assignment was superfluous in general case and incorrect in specific
case when the algorithm was given a lambda expression.
The copy assignment operator is defined as deleted for lambda
expressions.
Add minimal test for for_each_pixel algorithm to verify it compiles with
lambda expression.
The previous name is too generic and prone to variable shadowing,
causing compilation warnings (eg. vector named buffer in JPEG-s
reader::read_rows method).
* Applies patch from John Femiani submitted via Trac
https://svn.boost.org/trac10/ticket/2222 description:
It would be convenient if GIL views modeled ReversibleCollection concept.
In fact they almost do already. Without modeling this concept, it is
hard to use an image view with boost::range algorithms.
* Add related image_view concepts for Collection, ForwardCollection,
ReversibleCollection.
* Add tests for the new concepts.
* Add run-time tests for the new image_view methods.
* Apply patch from https://svn.boost.org/trac10/ticket/8896
* Add compile-time test of RandomAccessNDImageViewConcept
* Confirms the reported failure (tested with GCC 7.3 and clang 5.0)
* Verifies correctness of the patch
https://svn.boost.org/trac10/ticket/2979 description:
The description of the metafunction boost::gil::image_is_basic says that
it will return mpl::true_ if the image uses a basic view and
std::allocator<unsigned char>, however the implementation returns true
for any kind images that use any kind of allocator.

When loading PNG images with "simple transparency" the IO extension
should expland the contained alpha palette into a proper alpha channel.
Currenty the code queries if the image contains an alpha channel, which
is different from an alpha palette.
Fixes: #117
