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.
