SobGroup_GetDistanceToSobGroup(<sg_Group1>, <sg_Group2>)
This simple little function returns the distance between two sobGroups. It can be useful when you need to assess the relative distance of ships/squadrons with a given space object. -SunTzu

``````-- The function returns the distance between two sobGroups (as an integer); it returns nil if either of the sobGroups is empty
-- Arguments: <sg_Group1> and <sg_Group2>, names of the sobGroups
