Using odiff as a node dependency on mac

First off, I gotta say, I love this thing. Thank you so much for your work!

I'm currently using it as a dependency for my own open source Node project and it works perfectly on Windows but on a Mac I actually have to go into the node_modules/odiff-bin dependency folder and explicitly do an "npm install" or it won't work (I think it doesn't automatically copy the binary into the bin folder).
