Stochastic placement of cells (for TRISO fuels)

[smharper]

I'm working on a random geometry feature similar to what is described in LA-UR-04-8668 for MCNP. It is mostly finished, but I will wait on the PR until #313 is closed because it makes this feature much easier to implement.

Thanks @smharper. Once the 0.6.1 release is wrapped up, I'll start reviewing your hex lattice PR and this one as well.

This issue has gotten a little stale, and I think I would like to close it, un-resolved as it is. I implemented the algorithm, but I don't think it is worth merging in. It adds a lot of code and input bloat, and it also didn't provide a very random placement for the packing fractions we were interested in.

I think the superior way to model TRISO reactors is to make a script that automatically generates geometry.xml files with TRISOs explicitly placed in their positions. I was much happier with the results from that approach. I don't think it's appropriate to include such a script in the OpenMC repo (except maybe as an example?). So, yeah. I'm closing this.

Make it an example IPython Notebook!

That would be a great example that we could point people to!
