AbstractPathIterator

trait AbstractPathIterator[Item <: LeftLike[Item, Tree[Item, Section, CC]], Section, CC[_], T] extends Iterator[T]

Provides an Iterator from a given initial path that traverses the entire tree, allows both forwards and backwards iteration.

It specifically provides an up event, allowing consumers to "pop" the element stack
