Description
`ClassificationModel` crashes if the glTF model doesn't have indices.
For testing:
[Sandcastle](http://localhost:8080/Apps/Sandcastle/index.html#c=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)

Contributor guide
Research direction
Start with the linked Sandcastle reproduction and box-without-indices.zip, then trace the ClassificationModel crash while loading the glTF asset. Done means a glTF model without indices no longer crashes and the classification behavior works as expected.
