ContinuousMap.isEmbedding_postcomp

∀ {X : Type u_2} {Y : Type u_3} {Z : Type u_4} [inst : TopologicalSpace X] [inst_1 : TopologicalSpace Y]
  [inst_2 : TopologicalSpace Z] (g : C(Y, Z)), Topology.IsEmbedding ⇑g → Topology.IsEmbedding g.comp

If g : C(Y, Z) is a topological embedding, then the composition ContinuousMap.comp g : C(X, Y) → C(X, Z) is an embedding too.
