Since the FinSet equivalence requires ConstantToSetExtendsToProp, I've put FinSet.agda in theorems/homotopy, but that's not ideal. Perhaps it would be better to move ConstantToSetExtendsToProp to core and then put FinSet in core/lib/types?

FinSet= = Subtype=-out FinSet-prop

FinFS : ℕ → FinSet
FinFS n = Fin n , [ n , idp ]

What does the middle F stand for?

Thanks! This is great. Some lemmas in Pigeonhole.agda and FinSet.agda look quite essential and I might move them in to core/, but we can do that later.

Let me create a separate issue for this.
