v1.7.2 - Eliminate shortcuts duplicates
What's new
- Added usefull methods on *Vertex such as: delete / update incident edge.
- Eliminated shortcut duplicates, e.g.:
A -> B -> C on some iteration gives shortcut cost 205.
A -> G -> C on some iteration gives shortcut cost less 195.
So we should eliminate A-B-C and create A-G-C
