Create the Adaptive Layout Screen Type Classifiers

This story is only to create the classifiers for the Adaptive Layout screen, but not implement those routes, yet. Here is the mapping:

• FullyOpened and Expanded: List one third on the left, details two thirds on the right
• FullyOpened and number not selected: List only
• FullyOpened and number selected: Details only
• BookMode: List and details split half and half, from left to right
• TableTopMode: List and details split half and half, from top to bottom
• All else: List only

For now, remove the list of numbers screen (but do not delete the code), and only show the name of the mapping type on the screen, instead. This will be fixed in #5 (closed) with actual screens which implement the intended mapping types. This behavior is intended only to test that this story works.

It will not be possible to test a number of these scenarios, since the list is removed for this story. That is OK, just use the unselected state as the default value until the proper implementation is complete in #6 (closed).
