Morphism properties that are inverted by a functor

In this file, we introduce the predicate P.IsInvertedBy F which expresses that the morphisms satisfying P : MorphismProperty C are mapped to isomorphisms by a functor F : C ⥤ D.

This is used in the localization of categories API (folder CategoryTheory.Localization).

def CategoryTheory.MorphismProperty.IsInvertedBy {C : Type u} [Category.{v, u} C] {D : Type u'} [Category.{v', u'} D] (P : MorphismProperty C) (F : Functor C D) : Prop

If P : MorphismProperty C and F : C ⥤ D, then P.IsInvertedBy F means that all morphisms in P are mapped by F to isomorphisms in D.
