Motivation:
- GIL is part of Boost collection, so Boost version is sufficient
- GIL version makes little sense unless GIL becomes independent
- Two distinct version numbers, Boost's and GIL's, are confusing.
- Role of GIL's version number is not documented thus not entirely clear
The removal was discussed and agreed upon in this thread
https://lists.boost.org/boost-gil/2019/11/0346.php
The point belongs to core basic concepts in GIL, not an optional
utility. The tutorial starts with description of point.
Such core concepts are defined in dedicated headers which is quite
a useful convention that also makes the code structure clearer.
Remove from trivial point2 class superfluous empty destructor,
copy constructor, assignment operator.
Clean up point.hpp formatting (eg. respect line length limit).

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.
