A SceneStrategy that displays entries that have added dialog to their NavEntry.metadata within a Dialog instance.
SinglePaneSceneStrategy

A SceneStrategy that always creates a 1-entry Scene simply displaying the last entry in the list.

Cmn 
@Composable
fun calculateScene(entries: List<NavEntry<T>>, onBack: (count: Int) -> Unit): Scene<T>?

Given a back stack of entries, calculate whether this SceneStrategy should take on the task of rendering one or more of those entries.

By returning a non-null Scene, your Scene takes on the responsibility of rendering the set of entries you declare in Scene.entries. If you return null, the next available SceneStrategy will be called.

Parameters
entries: List<NavEntry<T>>

The entries on the back stack that should be considered valid to render via a returned Scene.
onBack: (count: Int) -> Unit

a callback that should be connected to any internal handling of system back done by the returned Scene. The passed Int should be the number of entries were popped.

Added in 1.0.0-alpha02
