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.

16a79cd567 Remove serde:🇩🇪:Error implementation for error::Error 
Serde forces us to be generic over which error our visitor returns, so we cannot return our error type.
So the implementation of serde's error trait is useless to us at this state.
