Demonstrate how to replicate MCNP-Go

[MicahGale]

I cam across this paper for MCNP-Go on arxiv: https://arxiv.org/html/2507.05659v1. They are claiming that MontePy is not able to handle their specific problem they are solving. My understanding of the problem is blending two files together, and transforming one file.

Clearly we haven't made the documentation clear enough to show this is possible. This would make a good demonstration problem for an example.
