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.
Using `self.tableView` doesn't really work here, because then the dictionary key is 'self.tableView', but NSLayoutConstraint gets bumfuzzled by the `self.`—I think it's looking at it as a keypath? In any case, I'd need to set a separate variable like `UITableView *tableView = self.tableView;` which is just overkill for this thing.
