C++11 on up Boost libraries

In my effort to set the meta information of 'cxxstd' for the appropriate 
C++11 on up libraries, my PRs for these libraries have been kindly 
merged to 'develop' by the library maintainers:

beast
callable_traits
context
convert
coroutine2
fiber
geometry
gil
hana
histogram
hof
json
leaf
mp11
nowide
outcome
pfr
process
safe_numerics
static_string
stl_interfaces
variant2
yap

If anyone knows of any other current library which is a C++11 on up 
library, please tell me. My testing showed that all other Boost 
libraries will work in C++03 mode, but maybe I missed some other library 
which is a C++11 on up library.

Needless to say other libraries have noted their attention to move from 
C++03 to C++11 in the near future. If any library does change the C++ 
mode necessary to use that library, I hope the maintainer(s) of that 
library will update the 'cxxstd' meta information appropriately.

If we can get the website to work properly using the 'cxxstd' meta 
information, end-users should be able to know immediately whether a 
Boost library is usable depending on the C++ standard mode their are using.
