Theorem cvmliftlem14 23828
Description: Lemma for cvmlift 23830. Putting the results of cvmliftlem11 23826, cvmliftlem13 23827 and cvmliftmo 23815 together, we have that  K is a continuous function, satisfies  F  o.  K  =  G and  K ( 0 )  =  P, and is equal to any other function which also has these properties, so it follows that  K is the unique lift of  G. (Contributed by Mario Carneiro, 16-Feb-2015.)
