Breadth-first, forward traversal for edges.
This traversal follows edges in their natural order from source to target visiting sibling edges before children. The advancing methods and operators (advance, next, etc.) stop only at edge enter events (ENTER_EDGE). Dereferencing the traversal object returns a graph edge node.
