Coincident Vertex Check

Hi Guys,

I'm looking for a script that checks for vertices sharing the same XYZ space as other separate objects. Generally it would 2 main modes.

1) Specify layers to compare and highlight vertices that are coincident. Alternatively, it could highlight the vertices that are not coincident.

2) Select multiple meshes and highlight vertices along Boarder edges that are not coincident with other meshes.

If you need more info let me know, but that's the core of the tool.
