merge
merging in new sets
folding new set representations into Verify
pushing verify heavy lifting into z3
also re-encoding all the "pervasives" in terms of ocaml types

recoded z3 pervasives in ocaml structures
trivial merge
delegating formulas to functions
function interface enhancements, some work on seq
switched from pkt->set to set->set, seems to be working better
re-added forwards_star
reachability, thoroughly untested but finally implemented
merge

more bugfixing
