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.

c631171ff0 Add comma operator and display implementations
+ Add comma token
 + Add tuple operator
 + Add tuple value type
 + Implement display for `tree::Node` and all related types
 + Add support for right-to-left chaining of operators with same precedence

The priority of chaining of operators with the same precedence remains left-to-right.
Only if two consecutive operators with the same precedence are right-to-left, they will be ordered right-to-left.

Implements #4.
