Merge branch 'handling-tcp-messages' of https://git.soton.ac.uk/plw1g21/robobin into handling-tcp-messages

Now all that you need to do with new nodes is add it into the robobin_launch and setup python files
Then colcon build (inside the ros2 root directroy)
source install/setup.bash
ros2 launch robobin robobin_launch.py

The steps to rebuild and run:
cd /GitLab/robobin/ros2
colcon build
source install/setup.bash
ros2 run robobin api_node

^A better way of doing it (not launching each node seperately) should be used. Research launch

Began the communication over TCP with the robobin and the app. Focusing on just one app instance for now but I will need to do more than 1

The graphs actually look quite clean right now, the scaling aspect will need to be made independent from the other axis (e.g. shrinking the horizontal shoulnd't affect the length of the graph, just the width).

okay so it looks like the problem with  the "ObjectDisposed" exception is related to accessing characteristics after they have been discarded, solution might be to have the "SCAN" be sent dring the scan wifi networks method, and just use the service saved instead of saving charactersitics.

App now has a basic structure and BLE support

See merge request !1

Added the side boxes with different text, they will have to become seperate components though (or children).
