Non-critical test wishlist

[choisant]

This is a list of tests that would be useful for spotting bugs, but should not block the new code from being merged into main. Add suggestions as they come to mind.

util.R

• Check logic of cluster/node setup for all cases of input "parallell".

learn()

• Check logic of assignment of nsamples, chains, nsamplesperchain
• Check that the maxhours functionality works, within a margin of error. (Is it even possbile to test this in a short amount of time? If not, we might want to have some tests that take a while not run automatically, but on demand.)
