Make it so that tapping a client shows a table with name and other notes.
This change gives the MA a way to see information about clients.  The view shows the name and age in the first section, then a section for the notes, and sections for the instructions and scheduled items.  The instructions sections show the context and (inner) instruction attributes, but not the effective or expiry dates.  The scheduled items section doesn’t get filled in.

The change modifies Main.storyboard and the Objective-C class PPRClientViewController.m.

In the storyboard, the change makes the table view grouped rather than plain.

In the class, the change adds knowledge about the groups/sections in the view and how they correspond to items in class instances.
