So GetUnits can be used to find any unit (air, map, or neither). This method can be more performant than GetUnitsInRange if the unit being searched is not found in large quantities on the map.
+  * 2D square search is currently broken and will find all units as long as they are close enough on X-axis, disregarding the Z-axis. Do not use this combination of parameters.
+  * The units "ern" and "pterosaur" will be picked up by a search looking for non-enemy built **non-impervious** units. If you need to avoid picking up those see if GetUnitsInRange is a more appropriate method (it doesn't pick up units in the air). If not, you may have to manually clean those from the list.
