There was a problem hiding this comment.
I have a removed a useless specialization and shorten a bit the names of the lemmas.

Motivation for this change
Add lemmas for integration on nondecreasing set sequences.
Although these lemmas are similar to
ge0_integral_bigcup, but I believe that it is worth adding because these lemmas can be used for not pairwise disjoint but nondecreasing sets sequences.It is especially useful for handling improper integrals, which are often read as an approximation by increasing sequence of sets in paper proofs.
I'm concerned that the names of lemmas are quite long. Are there shorter names for them?
Or, should we introduce an abbreviation for
nondecreasinglikendecr?Checklist
