made some more files compile
finished transition for RC, need Kt
further in Ktheory transition
More work done on uu0, sSet.v is added, surjections moved to hProp.v
some more work in Ktheory, blocked in RawMatrix
Merge remote-tracking branch 'upstream/master' into hom-hset-explicit
Ktheory compiles
Removed all occurences of match from uu0.v
new def of iso, stuck in functors_trans
made functors_.. compile again
everything compiles
removed print statements
removed comments
reactivated old isos as 'z-iso'
fixed two lemmas in Ktheory
fixed opp-opp-precategory proof in Ktheory/Precategories
