to reset the API:

1. connect to server with putty (username "ubuntu")
2. use command: "screen -ls"
	This shows a list of open screens (aka linux tabs)
3. If you see a tab called API and it says (detached) then go to step 4.
	otherwise perform the following steps:
	a. if the API screen says (attached) then run the command:
		"screen -D" The capital "D" detaches from all outside the screen.
	b. if there is no screen named "api" then use the command: 
		"screen -S api" This will create a screen named api and now go to step 5.
4. connect to the api screen with this command:
	"screen -r api"
5. you should now be in the correct screen
	a. if the script (CDVapi.py) is running then use the command "ctrl+c" This will stop the script
	b. once the script (CDVapi.py) is stopped run the following 2 commands to start it again:
		i. "export FLASK_APP=CDVapi.py"
		ii. "flask run --host=0.0.0.0"
6. detach from the screen with this: "ctrl+a" and "d"
7. you have now restarted the script and are detached from the screen... YAYY!!!!
