Appveyor /NEVER/ worked as any of the builds is taking up too much time.
This is quite confusing for the users/developers.
Travis is dead slow and it is virtually impossible to get any build
status in reasonable time. The free tier is now discontinued.
Codecov: never got a chance to get something good out of it.
Those builds were pushed to Boost.Test without any serious commitment
to maintain them on the long run.
- travis with valgrind, cppcheck, ubsan, codecov, covscan (future)
- appveyor with MSVC 2010 through 2017, cygwin 32/64, mingw 32/64
- README, LICENSE, etc.
- Fixed example Jamfile to build examples based on C++ features
This fixes#146
