#1396:

• Fixed loading of instances that did not specify coordinates (visual or actual ones)
• Turned coordinates into an OptionalValueParameter
• Added checks in relevant operators that throw an exception if they can neither find coordinates or distances
• Writing a message to the visualization if coordinates are not defined
