Removed the nib files and build collection/table views in code instead

Title says it all. The two nib files in the project worked in the example project, but got all crashy when using it as a pod. It's something to do with the bundle, and rather than fighting with it, I just yanked out the nibs: they only contained a table view and collection view, so it wasn't a complicated procedure.

@vokalinteractive/ios-developers could someone give this a review?

Since @lquigley is out this week, so PING PING PING co-sponsor @designatednerd.
I tend to prefer `NSDictionaryOfVariableBindings(_tableView)`, but if you prefer this, that's fine.
