e328adb97b Implement Node::iter_identifiers() 
This commit implements an iterator over the identifiers in an expression.
The identifiers are iterated pre-order, meaning that higher nodes in the tree are emitted first.
The identifier iterator is based on a general iterator over all nodes in an operator tree, which can be used for further featues.
