CategoryTheory.CreatesColimit

Dual of definition 3.3.1 of [Riehl]. We say that F creates colimits of K if, given any limit cocone c for K ⋙ F (i.e. below) we can lift it to a cocone "above", and further that F reflects limits for K. If F reflects isomorphisms, it suffices to show only that the lifted cocone is a limit - see createsColimitOfReflectsIso.
