Bindings for nanomsg-next-generation (nng)

This crate provides the FFI bindings for nng. In the future, the major and minor components of the version will be guaranteed to match the major and minor versions of the corresponding nng version. However, it is currently in active development along with the nng crate and so the versions do not match.

The nng library is compiled and linked by default. This can be disabled by setting default-features to false.
