> ISinkController and ISourceController's should pass wildcard generic versions
> of themselves to one another to increase flexibility of passing elements of
> common base types to one another:
> ISinkController<E> should use:
> public void add(E elem, ISourceController<?> controller); //instead of:
> public void add(E elem, ISourceController<E> controller);
> public void offer(E elem, ISourceController<?> controller); //instead of
> public void offer(E elem, ISourceController<E> controller);
> and ISinkController<E> should use:
> public void onFlowBlock(ISinkController<?> controller); //instead of public
> void onFlowBlock(ISinkController<E> controller)
> public void onFlowResume(ISinkController<?> controller); //instead of public
> void onFlowResume(ISinkController<E> controller); //instead of
> This allows for type conversions of elements between flow controllers.
