Add instructions on how to use OpenCastSwift in a new project

[kottkrig]

It would be great if there were a few pointers in the Readme on how to get a project with OpenCastSwift up and running.

Is the preferred way to use Carthage?

Agreed, I am lost here. How do we actually integrate this into an Xcode project?

was an xcode example ever availed or does anyone know how to use this library because the documentation doesnt make sense to me.
