Log Message:
-----------
* revamped contract grammar and interpreter - still a long way to go (array subscripts, functions, exception contracts,
open/closed intervals, sets, ...), but at least that's a better basis now. The big thing is that we have expressions
over operand values, including a generic "old(<expr>)" (so that we can store arbitrary exprs pre-exec)
