Optionally associated with a PasteUpMorph, provides a local scope for the running of scripts.

Once more valuable, may be again, but at present occupies primarily a historical niche.

Maintains a playerList cache.

Holds, optionally three 'standard items' -- standardPlayer standardPlayfield standardPalette -- originally providing idiomatic support of ongoing squeak-team internal work, but now extended to more general applicability.

	playerList	top
	allExtantPlayers The initial intent here was to produce a list of Player objects associated with any Morph in the tree beneath the receiver's associatedMorph. whether it is the submorph tree or perhaps off on unseen bookPages. We have for the moment moved away from that initial intent, and in the current version we only deliver up players associated with the submorph tree only. Call #flushPlayerListCache to force recomputation.
