Add bits and pieces to the Slying Agent client for checking availability and occulsion of mocap data. Needs compiling and teesting

Started process of converting the Flying agent client from the safe controller to the default controller, and streamlining things at the same time. Currently compiles and flys, but needs cleaning up and proper implementing of the take-off and land functions.

Remove the StudentGUI because it is was not updated to the new node naming convention and because it was re-factored as the FlyingAgentGUI

Convert all occurances of PPS Client to Flying Agenet Client. And adjusted all other occurances of PPS accordingly

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

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

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

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.

Added files for Picker node and integrated into student GUI, PPSClient, and Paramter service, needs testing

Loading of parameters from PPSClient, SafeController, and Custom controller now working, still need to debug messages from GUI buttons
