Re: how to debug, not understanding safe_primitive

Is there some documentation somehwhere of the possible members of the object
passed to new Pengine?


            var pengine = new Pengine({
                oncreate: handleCreate,
                onsuccess: handleSuccess,
                onerror: handleSuccess         % <= here, borrowing
handleSuccess...
            });


And is there a separate one for failure?  e.g. in more realistic world
the simple.html example would want to do something when q ran out of solutions.
