Theorem cvmliftlem10 30981
 Description: Lemma for cvmlift 30986. The function 𝐾 is going to be our complete lifted path, formed by unioning together all the 𝑄 functions (each of which is defined on one segment [(𝑀 − 1) / 𝑁, 𝑀 / 𝑁] of the interval). Here we prove by induction that 𝐾 is a continuous function and a lift of 𝐺 by applying cvmliftlem6 30977, cvmliftlem7 30978 (to show it is a function and a lift), cvmliftlem8 30979 (to show it is continuous), and cvmliftlem9 30980 (to show that different 𝑄 functions agree on the intersection of their domains, so that the pasting lemma paste 21008 gives that 𝐾 is well-defined and continuous).
