+The entire implementation is provided inline in the headers under the [gsl](./include/gsl) directory. The implementation generally assumes a platform that implements C++14 support. There are specific workarounds to support MSVC 2015.

it is simplest to just include [gsl/gsl](./include/gsl/gsl) and gain access to the entire library.
