Changes from Version 0.13.0 to Version 0.13.1

Release Date: 01.11.2011

### Bugfixes

- switched-off traffic lights are now put into the correct state
- vehicles with gui shape can now be used as router input
- updated tutorial networks
- fixed bug in duarouter which prevented use of multiple inline routes
- object-chooser no longer centers on unwanted objects

### Enhancements

- TraCI
  - Added the possibility to retrieve an induction loop's position (offset/lane) as suggested by Xiao-Feng Xie; thanks!
  - Added the possibility to remove a vehicle via TraCI
  - Added the description about how to add a vehicle via TraCI
  - Retrieve the number of still expected vehicles
- netconvert
  - added more control over joining junctions. You can declare nodes to be joined as well as exclude nodes from joining (see Networks/PlainXML#Joining_Nodes)
  - added option --osm.discard-tls (do not use tls definitions when importing OSM)
  - added option --junctions.join-exclude <STRING>[,<STRING>]* (junctions in this list are not joined)
  - added option --no-left-connections (do not build connections to left)
  - added optional attributes 'toLane' and 'fromLane' to connection-file element 'reset' (see Networks/PlainXML#Connection_Descriptions)
  - added importer for openDRIVE files, see Networks/Import/OpenDRIVE; many thanks go to Marius Dupuis from VIRES for allowing to use the example files for tests
  - added importer for matSIM files, see Networks/Import/MATsim (actually already in 0.13.0)
  - added new plain xml input/output format plain.tll.xml which holds information about traffic lights.
  - added option --geometry.max-segment-length <FLOAT> to restrict segment length by inserting additional geometry points
  - debugged brakedown on VISUM import
  - ignore connections for explicitly removed edges (instead of throwing an error)
- Simulation
  - Added Simulation/Output/Instantaneous Induction Loops Detectors
  - Simulation/Output/Induction Loops Detectors (E1) now also allow to generate values on per-vehicle type base
- jtrrouter
  - added Karol Stosiek's patch for reading more than one turn-definitions file; changes --turn-ratio-file <FILE> to --turn-ratio-files <FILE>[,<FILE>]*
- sumo-gui
  - can now switch traffic lights back on
- Tutorials
  - moved tutorials from <SUMO_HOME>/docs to <SUMO_HOME>/tests/complex for assuring their compliance with the current version; they should though appear in the release under <SUMO_HOME>/docs
  - added a tutorial on car-following parameter calibration
- Tools
  - added script tools/net/netdiff.py `<net1.net.xml> <net2.net.xml> <diff_prefix>` which creates the plain-xml differences of two sumo networks. The set of difference files can be loaded together with `<net1.net.xml>` to recreate `<net2.net.xml>`. This allows for advanced scenario management.
  - added tools for dealing with turn-ratios
- Documentation
  - restructured wiki-pages
  - new static HTML docs generated from the wiki

### Other

- updated gl2ps to version 1.3.6
- removed MSMsgInductLoop; the functionality was almost the same as for a plain MSInductLoop just that an additional string wasgiven; the functionality can be easily obtained by using proper ids and mapping them to "messages"
