Hello,

I'm adding an OBJ model file of the Utah teapot [1] (a standard 3D test model) 
to the project for use in unit tests and code examples. The file I used was 
generated by Nate Morrical at the University of Utah [2] from the original 
surface descriptions from Martin Newell in 1975. Neither the files from Nate 
nor the original surface descriptions include a license. I reached out to Nate 
about using his model in the project and he suggested that the license is CCO 
[3], i.e. public domain, but that I should check with SIGGRAPH to verify since 
they host the original files. I've emailed SIGGRAPH but I'm not very optimistic 
about getting a reply.

 Does anyone know how to add a proper license and attribution for this file in 
the project? Where does it need to go? If it truly is in the public domain, do 
I need to even add anything? RAT does not complain since it treats the file as 
binary.

Regards,
Matt J
