MorphScope class

The registry of tags and flights. Installed once near the top of the tree (not necessarily above the Navigator, but inside MaterialApp). A flight's shuttle renders in the NEAREST enclosing Overlay, so a nested navigator keeps its flights inside itself; in a single-navigator app that is the root overlay anyway. Also serves as the TickerProvider for all flights.
