Adjusted flying agent GUI behaviour for coorindator mode to be able to use the increment setpoint buttons in a meaningful fashion

Changes to comments in PPS Client (attempt to make style consistent with controllers), and added Emergency stop button to GUI

Tested to be working and added highlighting the tab label for the controller that is operating. Next step is to add tabs for the remote and picker controllers, add service for getting the currently operating controller, and switch and PPSClient from the safe controller to the default controller.

Added the custom button support to the new GUI, and added a get setpoint service. The Default and Student controller tabs are now fully integrated for the agent and coordinator mode. Needs testing.

Added menu items to hide show controller tabs and buttons. The functions should be genrealised a bit to make adding more controllers easier

Setpoint changes now generalised through the GUI for the Default controller. Needs more extensive testing. Next step is to get that current controller state when the corrdinator is coordinating only one agent

The coordinator row and (dis-)connect,  start-stop bar are now fully connected and fully generalised for operating as both an agent and a coordinator GUI

GUI STUFF: The top banner and motion capture pose data is now connected to the properly to the coordinator

Added things to GUI: red rectangles to indicated an occluded measurement, and unavailable image for battery and flying state

Prepared the Qt side of things for connecting the default and student controller tabs with ROS. Next step is to add and test the ROS-side code

Added some comments to the Vicon data Publisher. Important to note that the ROS_NAMESPACE environment variable needs to be set on the teacher computer

Small changes to make the GUI look nicer. Added an emergency stop button. It needs to be connected, given a proper image, and made hidden for when launched as an agent

Yaml connections working (for student and demo controller), and title is now proper. Ready for testing on real system before cleaning up the controllers and their interface

Connection between Coordinator and other components of GUI now working for passing around the agentIDs to coordinator. Next step is to clean things up, add all the necessary connections, and test.

Started connecting the Connect Start Stop Bar of the GUI. Now needs some GUI settings to be changed with Qt

Have setup the basic framework of the coordinator connections. Next step to connect all GUI buttons for (dis-)connect, start,stop,off,and select controller. And then test.

Finished setting up the Battery monitoring node and new parameter service style to match. Needs a GUI reload Yaml to be added and needs to be tested.

Battery monitor connected to new style of parameter service interface. Compiles by is not able to call the service client.

Corrected the variable name mis-match for the FAQ about getting data from Vicon.…
