Module sub_object 

Typed sub-object reference and sub-object selection set. Typed sub-object reference and sub-object selection set.

[SubObjectRef] is the single canonical way to identify a face, vertex, edge, or point-cloud point relative to its parent object. It is carried inside PickHit::sub_object and used as the key type in [SubSelection].

[SubSelection] is the sub-object counterpart to crate::interaction::selection::Selection. Typically an app holds both: Selection for which objects are selected, SubSelection for which faces or points within those objects are selected.
