Draft: gui_circulararray cleanup

Small spacing fixes like imports in separate lines
for more clarity, the module docstring,
and the position of the license.

Remove unnecessary check for the graphical interface
as this command should be imported when the interface
is already up and running.

Use proper `ToDo` class instead of importing `DraftGui`.
