Build fails on macOS Sierra

[crazyquark]

The build fails on macOS Sierra because it tries to include <tr1/unordered_map>.
This was on version 2.0.2.

I've created a PR that fixes this:
#33

As of macOS 10.12 Sierra, the default is now libc++ and libstdc++ is deprecated. libstdc++ is quite old, v4.2.1, and predates C++11 (hence the tr1 headers). If you're going to be using this code long-term, it'd be worth the time to at least make it C++11 compliant (i.e. #include <unordered_map>)

This module can't be build on MacOS X (10.11.6) when using v8 (works fine with v6 though). We have some dependencies on hashtable so I'm hoping the package maintainer will create a new build soon...

Any update on merging and releasing this? I could use it too. It won't build on macOS.
