This small tutorial is supposed to be a minimal working example for running Pigeons on a Unix machine. I have used the CRBD model in the example mainly since it is a biologically interesting model but has simple outputs. However, our local MCMC kernel (standard lightweight MCMC) is very poor for this model so the samples we get are not very convincing. Swapping for a different model is very easy so feel free to suggest something else.

The Pigeons PR Julia-Tempering/Pigeons.jl#374 is not merged yet but soon will be. In the meantime you have to install Pigeons from that PR for the tutorial to work i.e. typing ] in the Julia REPL to get into the package environment and then

add https://github.com/ErikDanielsson/Pigeons.jl/#treeppl

should install the correct version for you.

Note also that I've added two packages katex and remake-math for writing LaTeX. I could get away without using them, but I thought it was nicer this way even if we want the math to a minimum.
