Shouldn't the traits in fuzzer.rs just be a public function?

[tokatoka]

Evaluator, ExecutionProcessor, EvaluatorObservers.

These traits are causing problems for me and I can't continue on #2872
and i don't see any reason why we can't just use public function instead.
We can just use the implementation of StdFuzzer for these traits.

Functions cannot be overridden right?
Or do you want to pass them in somehow?

[tokatoka]

i don't think functions Evaluator, ExecutionProcessor, EvaluatorObservers. should be overridden

[tokatoka]

btw this is another problem cyclic dependency.
fuzzer uses event manager inside. but event manager calls into fuzzer function too.

@addisoncrump
opinion?

another solution to #2872 is to remove EM from all these traits.
ExecutionProcessor<EM, I, OT, S> to ExecutionProcessor<I, OT, S>
and
EvaluatorObservers<E, EM, I, S> to EvaluatorObservers<E, I, S>
and move them to each function
but this sounds wrong to me.
