Add Lane Edditing

[DeznekCZ]

Hi MacSergey,

I'm not able to compile code, but I have an idea to extend this tool for editing lanes. First test will be to lane inversion of connected segments to node. If It will work I can continue on this task to make it more usable.

(If is possible to add help to setup workspace, I'll accept it and then I can test my changes directly)

Thanks DeznekCZ
