Robot lot contains manually placed parking spaces

[erxor]

According to the functional requirement (#8), the program should show a comparison of the number of parking spaces between a standard car park and the Pit Stop solution. To do this, the user should initially manually mark the parking spaces.

When pressing the 'Make robot lot' button after manually marking some spaces, the manually set parking spaces still remain in their locations in the robot lot.
