Minor fixes arising from the first practical class of Spring semester 2019. Mainly relating to loading of paramters on first run, and also the integrator of the default controller

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

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

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.

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

Started on making the Parameter Service more generic, compiled and tested, still needs full implementaiton

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