Implement UIResponder Delegate methods resolves #12
Migrate all UICollectionViewDelegate logic down into the ContactCollectionView and out of the MBContactPicker
Merge branch 'release/0.0.7' into develop
Merge branch 'master' into develop
Fix some bugs that prevented the MBContactPicker from working out of the box, it was creating a ContactCollectionView that was always 0 points tall because [self updateCollectionViewHeightConstraints] was no longer getting invoked.
Moved UICollectionViewDataSource implementation into the ContactCollectionView.  Some things still need to be cleaned up, added as warnings
Change from a contact object to a contact model protocol
Re-implement reset of entry cell after contact is selected
Add warning for UITextField delegate method that probably needs to be moved
Indentation
Update README.md with new instructions, add property to contact object in sample code.
Fix regression in entry cell sizing
Move UITextFieldDelegate from MBContactPicker to the ContactCollectionView, expose a method in ContactCollectionViewDelegate that gives the delegate access to text changes in the entry cell
