* ./katabatic: - Change: In KatabaticEngine, the containers used to store the "nets to route" is changed from a vector<> to a set<> sorted by the Nets names. Uses more memory but allows much faster Net deletion. - New: In _loadNetGlobalRouting(Net*), detect non-routed Nets. A Net is considered as unrouted if it's 10 first RoutingPads have no slave Segment. The Net is withdrawn from the set of Nets to route. - Bug: In GCellConfiguration::_GCell_1G_1L1(), correctly compute the access flag passed to _GCell_rp_Access(). - Change: In AutoContact::restrictConstraintBox() adds "warnOnError" parameter to shut down warnings. - New: KatabaticEngine::_computeNetConstraints() now also returns a set<> of segments on which constraints are incompatibles. All the NetConstraints related functions are modificateds accordingly. - Change: In KatabaticEngine::_loadNetGlobalRouting(), create dogleg on overconstrained Segments computed by a call to _computeNetConstraints(). Overconstraineds Segments can occurs when a global is directly connecting two punctual RoutingPads (see "ieee_division"). As a side effect, and to avoid looping each Net is revalidated *before* making any dogleg. So Nets are revalidated one by one instead of alltogether. - Change: In AutoSegment::_toConstraintAxis(), do nothing if constraint interval is empty.
