            Welcome to the EWB Drone Navigation Algorithm GUI!

            First, click to set the boundary vertices of your region,
            without clicking on the first vertex again at the end. Then, 
            click 'Draw Path', which will prompt you to enter the stride 
            length in pixels. Enter the desired length (be reasonable!) 
            and hit OK.

            Alternatively, provide a stride length in the command prompt 
            by running `python display.py [stride]` where [stride] is 
            the desired length.

            The algorithm should display the planned path through the 
            region. Hit 'Reset' to reset the screen.
