COLLADA and TSShapeConstructor problems

Hello everyone,
I've been working on a simple object to get it working with LODs using a skinned object and the TSShapeConstructor. I've read all the documentation about the TSShapeConstructor. Everything is clear except some things that I coudn't understand.

First what is "object" and what is "mesh"???

Quote:
# object: An object is a collection of meshes, each at a different detail level. Each object is attached to a certain node, and is rendered at that node’s current transform.
# mesh: A mesh is a piece of geometry, and may be a rigid body or a skin (vertex weighted mesh). Each mesh is associated with an object and a certain detail level.

this doesn't say much to me. In my sample *.dae file a teapot is the skinned mesh. So what is it in fact?
Also there is no sample hierarchy that must be achieved usign the TSShapeConstructor's methods.

At all could someone tell me what to do via some sample scripts to get a simple skinned teapot working LODs?
All this new system TSShapeConstructor might be quite easy to work with but I can't get started.
I have setup my model using the DTS hierarchy scheme. When I load it in the Shape Editor at the "nodes" tab I don't see the detail nodes.

I hope you got the idea of this my post here. I can't get started at all. So please someone provide some sample scripts for a single skinned mesh with LODs.
