--[[ Element: Combat Icon
 Toggles the visibility of `self.Combat` based on the player's combat status.

 Widget

 Combat - Any UI widget.

 Notes

 The default assistant icon will be applied if the UI widget is a texture and
 doesn't have a texture or color defined.

 Examples

   -- Position and size
   local Combat = self:CreateTexture(nil, "OVERLAY")
   Combat:SetSize(16, 16)
   Combat:SetPoint('TOP', self)
   
   -- Register it with oUF
   self.Combat = Combat

 Hooks

 Override(self) - Used to completely override the internal update function.
                  Removing the table key entry will make the element fall-back
                  to its internal function again.
