Test the "sewing up" of the triangles.  Because I'm using equalateral triangles rather than quads, the sewing is different.  And because how you put together "rings" of different resolution triangles (starts with a hex of them, then go out from there in rings), the sewing only needs to happen on one side.  I'm just verifying that it is working.

One more piece needs to be done to finish sewing, and that is to share the overlapping vertexs to prevent any gaps.
