MATSim Code

code cleanup

bugfix

changed method addSeries() from protected to public, so it can be really used...

removed org.matsim.controler.IterationCleanup. The class wasn't in use any more for over a year, support for it in the Controler was removed a long time ago, and the structure how it was implemented/integrated into the Controler was out-dated as well...

added org.matsim.utils.charts, some simple classes to generate basic charts with a simplified API.

code cleanup.

removed no longer used class

Replaced PriorityQueueBucket (PQB) in Dijkstra with regular java.util.PriorityQueue (PQ), as the PQB was actually slower than the regular PQ. As the PQB was passed as parameter to many methods, lot of other classes that intherited from Dijkstra had to be changed as well. The interface KeyComparator was only used by PQB and could be removed afterwards. In the ReRouting-TestCase, one single plan had a different route, but with the same travel time, which may be due to a sorting issue with similar keys, handled differently between PQB and PQ. Similarly, the Snapshot of the RouterVis had changed, but visually it still displays the same.

removed unnecessary import-statement.

Use clone() on arrays when returning them in public getters/setters, as not to expose internal data structures to the outside.
