OpenRMF

1) Using `traffic-editor` to generate simulation world

we are using the previously generated map file using slam_toolbox to create and annotate 2D floor plans with robot traffic along with building infrastructure information using this tool

2) Generating world file

By using the *.building.yaml file generated from traffic-editor to generate .world file.

cd butlerbot_rmf_gazebo/config/
ros2 run rmf_building_map_tools building_map_generator gazebo cafe.building.yaml cafe.world .

Seperating worlds, models into different folders #TODO: configure this step in cmake

3) Creating a launch file to view this world in gazebo

Launch the world generated using traffic editor

ros2 launch butlerbot_rmf_gazebo simulation.launch.py
