Hi all,

I've already finished my GSoC task, which is "P5. Better data structure for selections".
In details I've done:
- created ObjectSet class to be a base class for Selection - ObjectSet has a multi_index_container from Boost (http://www.boost.org/doc/libs/1_61_0/libs/multi_index/doc/tutorial/basics.html) instead many containers like vectors, lists and sets
- created appropiate tests for this class in GoogleTest framework
- replaced some functions returning vector to return range (http://www.boost.org/doc/libs/1_61_0/libs/range/doc/html/range/reference/adaptors/introduction.html)
- replaced own children list implementation from SPObject with boost intrusive list
- added tests for new children list
- replaced parameters in some functions (Selection with ObjectSet)
- improved spray tool (there is no need to use selection now)

Changes are ready and exist on my branch (https://code.launchpad.net/~adrianboguszewski/inkscape/adrian). They will by merged to trunk in the near future. I'm waiting for c++11 flag :)

As I still have about three weeks till GSoC end, I decided to start another project, which is new SAX parser.

Best regards,
Adrian
