- broken! too much code in Java method
- fixed Db string ids
- convert all pathway rules to PSL
TO DO (from Steve):
- split disjunctive rules (Family) into pairwise parts: Active(G1) => Active(G_OUT); rules are all soft-OR-ed together
- conjunctive rules: may want to split into pairs as well (with smaller weights): if G is active, there is some (additive) evidence the complex should also be active;  since it's unlikely that all disjunction operands would be asserted simultaneously / the rule may thus never fire
