v0.1.0

@trevorlinton Here's a pull request issue that we can work towards moving into `master` branch. I have a few comments which I'll add inline below.
So this probably isn't documented properly, but the idea of this file is to have a "global" mode for NodObjC, such that you do `require('NodObjC/global')` and from there on, `framework()` and any loaded Objective-C symbols get added to the global scope rather than the exports object returned from the require call.

So first question is "are loaded symbols still being attached to the `lib/global` object like before? And if yes, can we restore this root-level `global.js` file so that the "global" mode still works?
