     59 A basic app showing how to use the Transition framework introduced in
     60 KitKat. The app shows radioboxes to select between different Scenes,
     61 and uses various ways to transition between them.

     67 A Scene is an encapsulation of the state of a view hierarchy,
     68 including the views in that hierarchy and the various values
     69 (layout-related and otherwise) that those views have. A scene can be
     70 defined by a layout hierarchy directly or by code which sets up the
     71 scene dynamically as it is entered.
     72 
     73 A Transition is a mechanism to automatically animate changes that
     74 occur when a new scene is entered. Some transition capabilities are
     75 automatic. That is, entering a scene may cause animations to run which
     76 fade out views that go away, changeBounds and resize existing views
     77 that change, and fade in views that become visible. There are
     78 additional transitions that can animate other attributes, such as
     79 color changes, and which can optionally be specified to take place
     80 during particular scene changes. Finally, developers can define their
     81 own Transition subclasses which monitor particular property changes
     82 and which run custom animations when those properties change values.
     83 
     84 TransitionManager is used to specify custom transitions for particular
     85 scene changes, and to cause scene changes with specific transitions to
     86 take place.
