doAmbiguityLinks()

template<typename SrcT, typename DestT>

void egAmbLinkHelper::doAmbiguityLinks	(	const EventContext &	ctx,
		DataVector< SrcT > *	srcContainer,
		DataVector< DestT > *	destContainer )

Needs the same logic as the ambiguity after building the objects (make sure they are all valid)
