+/// from normal analyses because any available implementation of the group will
+/// be used if it is available.
+///
+/// If no analysis implementing the interface is available, a default
+/// implementation is created and added.  A pass registers itself as the default
+/// implementation by specifying 'true' as the second template argument of this
+/// class.
+///
+/// In addition to registering itself as an analysis group member, a pass must
+/// register itself normally as well.  Passes may be members of multiple groups
+/// and may still be "required" specifically by name.
+///
+/// The actual interface may also be registered as well (by not specifying the
+/// second template argument).  The interface should be registered to associate
