Lets meet about version control for Xcode, as well as core data

Building on the first 2 meetings, we will discuss the version control that you get with Xcode 4.2, as well as core data, the native database abstraction layer. The goal will be to change the current POC app to work with Core Data instead of using the array.

We've been keeping things at a pretty basic level, and having a great time discussing Xcode!
