Arbitrary Object Processing

[cdmpants]

When running Process Model, check for objects inside arbitrary, non-LOD collections, or no collections at all, and add them to the LOD_0 collection. If a LOD_0 collection doesn’t exist, create one, with a parent collection with a generic name like “Object”.

Make sure the generated LOD_0 collection has the "Object_" prefix as well, so "Object_LOD_0", to make it consistent with Toolbox's typical naming conventions.

This will let users more easily process arbitrary, non-LXF-imported models.
