Implementing costmap_2d layer with pre-Hydro costmap.
The project I'm working on uses a costmap that was created before the new costmap_2d implementation. I'm working in Indigo now, but the costmap hasn't been upgraded at all since the ROS version switch. I'd like to implement a new layer, so I'm just trying to get the tutorial Grid Layer set up. I worked through the 'Creating a New Layer' tutorial, but I'm not really sure what else I'll have to add in order to implement this new layer. I know the new code compiled during the catkin_make, but I'm not sure where to add the new layer. Will I need something in the C++ code that creates the original costmap object? Any yaml or xml changes that need to be made? Thanks!
