couldn't figure out how to handle sortstate, eventually put it into
bsort class. should be split into timeraction and steppable. and there
shouldn't be a random steppedbsort in App
now using App and SFML's loop, but haven't properly set up data vs
logic vs UI yet.
added setuptimers()
sortdata currently member var, should either make vec, or attach it to
a different object
