Cocoapods

Hi @profburke.

Here is a version which pulls the Lua dependencies from CocoaPods. The only caveat is that the latest lua available on pods is 5.2.3, and not 5.3.0 like you had. We can wait for 5.3.0 to be available, but just waned to put this out there, as another example of the workflow.

Let me know your thoughts, and thanks for putting this project together.
