changing the proof procedure for parameters; adding a testcase for negation and parameters; adopting print_tac to the latest function print_tac' in the predicate compiler

adopting proposed_modes; adding a new dimension of complexity for nicer error messages; tuned

check if equations are present for all functions to avoid low-level exception later

anti_sym -> antisym

optionally trace theorems used in proof reconstruction

added arithmetic example using div and mod

bump up Nitpick's axiom/definition unfolding limits, because some real-world problems (e.g. from Boogie) ran into the previous limits;
the limits are there to prevent infinite recursion; they can be set arbitrarily high without much harm

merged

comment out debugging code in Nitpick

fixed bug in Nitpick's handling of "The" and "Eps" when the return type is a "bool"
