A finset-valued version of set.interval.


I need this for the proof of the van den Berg-Kesten-Reimer inequality on page 2.

Since you've added this new def alongside Icc, can you go through lemma like prod.Icc_eq and add their interval counterparts?

I think at least one of these files should have a docstring that mentions the new interval too.

Probably you should look at every locally_finite_order instance, and add interval lemmas if there are already Icc lemmas nearby.

I've started doing so but the PR would become huge. Do you mind making that a separate PR in order not to block my progress on vdBKR?
