Flag: are our decoration items initially present in our location? By default they are, but there may be circumstances (e.g. changhe from night time to daytime) when we want them to start out off stage.

A list of the Decoration objects created by this Scenery object at preInit.

The list of vocab, descriptions and optionally notImportantMsgs for each of our Decoratio objects. Each item in the list should be a list of two or three items of the form *. [vocab, desc]
or [vocab, desc, notImportantMsg] *. vocab and notImportantMsg must be supplied as single-quoted strings. desc can be either at single-quoted string or an anonymous method or function. The vocab string should be defined as for the vocab string of a normal Thing. *. The scenList property can be defined through the Scenery template.

Flag; should the decorations we create be visible in the dark. By default they're not, but if, for example, we're creating a series of sky objects for use at night time, such as sky, moon, and clouds, we might want them to be.

PreInitialization of a Scenery object creates the Decoration objects defined in our ScenList property.

For the base Scenery class, move our new object into our own location.

If our decoration start offstage or have been moved elsewhere we can restore/move them to our location by calling makePresent() or makePresent(true). To remove them all call makePresent(nil).

We can call moveInto() on us to call it on each of the decorations we have created. Tbis might most usefully be used with loc = nil to move all our decoration objects off-stage.

For the base Scenery claas, create a new object of the ScenItem class and returnb a reference to it.
