Floris van Doorn	afdcf7cb71	backport some changes from lean 3 ... ap_compose' is reversed, and is_trunc_equiv_closed and variants don't have a type class argument anymore	2018-09-10 17:05:29 +02:00
Floris van Doorn	ddef24223b	make pointed suspensions, wedges and spheres the default (in contrast to the unpointed ones), remove sphere_index ... All HITs which automatically have a point are pointed without a 'p' in front. HITs which do not automatically have a point do still have a p (e.g. pushout/ppushout). There were a lot of annoyances with spheres being indexed by N_{-1} with almost no extra generality. We now index the spheres by nat, making sphere 0 = pbool.	2017-07-20 15:02:09 +01:00
