Incorporating prior knowledge

[casv2]

Everyone agrees that the coefficients needs to be regularised (or 'small') and this is incorporated into the BRR/ARD prior. It's also possible to incorporate other 'expert' information into the prior. One idea floating around which @WillBaldwin0 is looking into I think is to fit to dimer data first, incorporate it into the prior, and then do the full solve. We'd need an interface allowing us to provide this prior c-vector before fitting. This procedure is quite simple and turns out to be really only a change of variables.

Probably worth it to wait and see what Will thinks about this idea first before implementing it properly.

No need to wait - I’m very keen on this. I have student lined up to work on it, but I want to coordinate with Will - no point doing the same thing twice.
