I added the (currently useless) text boxes for the user to put in the direction and distance they would
want the robot to go. I then had those widgets be displayed in the main window next to the draw area.

I also removed the minimumSizeHint and sizeHint functions in both the MainWindow and DrawArea class
because they weren't doing anything and instead replaced them with the functions
QWidget::SetMinimumSize(int w, int h) and QWidget::SetMaximumSize(int w, int h).
