BasicChair

A chair is an item that an actor can sit on. When an actor is sitting on a chair, the chair contains the actor. In addition to sitting, chairs can optionally allow standing as well.

We define the "BasicChair" as something that an actor can sit on, and then subclass this with the standard "Chair", which adds surface capabilities.

class BasicChair : NestedRoom

A list of the allowed postures for this object. By default, we can sit and stand on a chair, since most ordinary chairs are suitable for both.

A chair's effective follow location is usually its location's effective follow location, because we don't usually want to treat a chair as a separate location for the purposes of "follow." That is, if A and B are in the same room, and A sits down on a chair in the room, we don't want to count this as a move that B could follow.

A list of the obvious postures for this object. The only obvious, default thing you do with most ordinary chairs is sit on them, even they allow other postures. Something like a large sofa might want to allow both sitting and lying.

This list differs from the allowed postures list because some postures might be possible but not probable. For most ordinary chairs, standing is possible, but it's not the first thing you'd think of doing with the chair.

For "get on/in" / "board", let our default posture object handle it, by running the appropriate nested action that moves the actor into self in the default posture.

by default, objects dropped while sitting in a chair go into the enclosing location's drop destination

Perform entry in the given posture. This carries out the common actions for SIT ON, LIE ON, and STAND ON.

Run the appropriate command to remove us from this nested container, as a replacement command.

Try an implied command to move the actor from outside of this nested room into this nested room. By default, we'll call upon our default posture object to activate its command to move the actor into this object in the default posture. For a chair, the default posture is typically sitting, so the 'sitting' posture will perform a SIT ON <self> command.

Remove an actor from the chair. By default, we'll simply stand up, since this is the normal way out of a chair.

Verify that we can enter the chair in the given posture. This performs verification work common to SIT ON, LIE ON, and STAND ON. If this returns true, the caller should inherit the base class default handling, otherwise it shouldn't.
