fix lambda-lifting: take level of bound variables into account and also apply bound variables from outer scope
2010-12-16, by boehmes

2010-12-15, by boehmes
fixed checking and translation of weights (previously, weights occurring in terms were rejected, and weight numbers were unintended translated into Vars)
2010-12-15, by boehmes
the functions term_of and prop_of are also needed in earlier stages, not only for Z3 proof reconstruction, so they really belong in SMT_Utils

2010-12-15, by hoelzl
