* Baby steps * Compile without implementations * Compile combined_grids * Compile part of principal node map_merge.cpp * Finish 90% of main node * Move ros::names implementation to own file * Replace ros1 while loops threads with ros2 timers * Fix checking of map type for adding robots. bypass mutex for now * Working version without init poses, still verbose logs * Add namespace to explore_lite Add tb3 launch files for multirobot tests Finish multirobot map merge with poses known * Add files for tb3 demo * Fix launch file for demo with robot poses * Fix comments on locking * Change deprecated Ptr to SharedPtr in ros2 msgs variables * Change ConstPtr to ConstSharedPtr for ROS2 * Fix minor warnings in explor_lite * Attempt fix slam toolbox * Add launch and remove old ones * Add copyright * Add readme with instruction on how to run the demo in sim * Fix readme and port from_map_server launch file * Fix QoS for suscriptions with TRansientlocal
