PathPlanningInterface

Intro

Some stuff.

Notes

I updated the way the path planner works. After the scene is changed the path planning system needs to be refreshed. This will process all of the newly added obstacle. I fixed this by adding gEngine->getPathPlanner()->refresh(); to the ScenarioModule::generateNextSubspace() method. Things need to be refreshed right after the obstacle are added and before the agents are added to the scenario.
