Keep alternating trees between stages
...
Delete only the trees that are involved in an augmenting path.
Keep the other trees and reuse them in the next stage.
This gives a big speedup on many cases such as random graphs.
The code is a mess, needs to be cleaned up.

Do not check edge slack during scan
...
Tight edges are not used immediately during the scan.
Just like other edges, tight edges are tracked in priority queues
and are used later through a zero-delta step.
This simplifies slack calculations.
