These leaf functor specializations are used to notify a field or expression that it is going to be read and, therefore, needs to update itself.
The first LeafFunctor represents default behavior, which is to do nothing.
Fields with engines that store internal fields AND don't copy those fields' relations to its list must provide a specialization to get the internal fields to update.
NOTE: we don't use the ExpressionApply machinery here because this really operate on the engines.
