New branching scheme #121

Closed tkralphs closed 1 year ago

tkralphs commented 1 year ago

This PR is to refactor the way branching is done. The function that selects branching candidates is now much more transparent and a new option to prioritize branching on lower-level variables has been introduced. The tailoff detection that determines when to branch has also been improved.
