GSL
Guidelines support library
...This repo contains Microsoft's implementation of GSL. The entire implementation is provided inline in the headers under the gsl directory. The implementation generally assumes a platform that implements C++14 support. While some types have been broken out into their own headers (e.g. gsl/span), it is simplest to just include gsl/gsl and gain access to the entire library. This project makes use of the Google Test testing library. Please see the ThirdPartyNotices.txt file for details regarding the licensing of Google Test.
