Floris van Doorn	6cdbc0f79f	feat(pointed/equiv): add more theorems The theorems are mostly about the interaction between pointed equivalences and pointed homotopies Some of these theorems were missing for (unpointed) equivalences, so I also added them there	2016-02-22 11:15:39 -08:00
Floris van Doorn	facd94a1b4	feat(hott): various changes more about pointed truncated types, including pointed sets. also increase the priority of some basic instances that nat/num/pos_num/trunc_index have 0, 1 and + (in both libraries) also move the notation + for sum into the namespace sum, to (sometimes) avoid overloading with add	2016-02-22 11:15:38 -08:00
