* Fixes issue with dereferencing operator issue #491 introduced in PR #513
dereferencing operator added in PR#513 returned a copy of the object
instead of reference to it.
Adding decltype(auto) as return type of operator* fixes this issue.
* added more tests for not_null::operator*
Project files were not following the clang-format style. For people
using IDEs were clang-format is always run after a save this would
cause unwanted changes.
This commit only applies "clang-format -i" to files.
* Added support of not_null<smart_ptr> comparison
* The return type of not_null comparison operators is determined using SFINAE
#474
* tests for gsl::not_null comparison were added
* not_null comparison tests were rewritten to compare pointers to objects located in the same array
* not_null<shared_ptr> comparison was simplified

whether using it from the development folder, from the installation
folder or from being copied into a project.
#include <gsl/gsl.h>
Updated headers/tests/instructions/cmake build accordingly
This PR should address https://github.com/Microsoft/GSL/issues/277 (less
the renaming of gsl itself)
Also removed unused constant member variable that seemed to be there
to prevent maybe_null_* being used with anything other than a pointer,
which is being taken care of with a static_assert now.
