With this major revision, I consider code is now stable:  - circle event now uses rb-tree code rather than sorted array  - this allowed to remove numerous code path etc.  - fixed serious bug introduced in an earlier revision in Voronoi.addBeachsection() (diagram computation failed when two or more first sites shared y value)
