--usage examples
--single unit refueling, all tanks
khRefuelUnit(ScenEdit_UnitX()) -- used inside a trigger refuel the triggering unit.
khRefuelUnit(ScenEdit_GetUnit({guid="SomeValidUnitGuid"})) -- get unit first, feed unit wrapper to function.

-- Side version: Feed it the name of the side, it will refuel all units of unittype to max capacity.
khRefuelSide('Blue'); -everything.
khRefuelSide('Blue',"Aircraft"); --only aircraft
khRefuelSide('Blue',"Aircraft",3101) --only aircraft with subtype code 3101 (bomber)
khRefuelSide('Blue',"Weapon",2001) --only weapons with subtype guided weapons.  (Yes you can refuel missiles if you really want too, handy for debugging purposes)
