Ajustement de frontières

[hhirtz]

• [x] show a RCB partition as svg
• [x] show where part frontiers intersect
• [x] list of possible moves
  • [x] list individual segments
  • [x] combine segments together and test imbalance/lambda cut
• [ ] derive the imbalance of the partition from the split tree & list imbalance gains
• [ ] derive the edge cut from the split tree & list edge cut gains
• [x] derive the lambda cut from the split tree & list lambda cut gains
• [x] show the gains
• [x] get the best gain and make the move

reworked the lambda cut gain computations and now i cannot find cases where there is a move of positive gain
