### void expandBoundingBox(BoundingBox &bb) const

Updates bounding box to expand search space when routing is failing to find possible route.
As part of `router2` implementation, during congestion update, every third time a net fails to route, this method is executed to expand the bounding box to increase the search space.

Default implementation expands by one tile in each direction.
