--[[ Element: Master Looter Icon

 Toggles visibility of the master looter icon.

 Widget

 MasterLooter - Any UI widget.

 Notes

 The default master looter 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 MasterLooter = self:CreateTexture(nil, 'OVERLAY')
   MasterLooter:SetSize(16, 16)
   MasterLooter:SetPoint('TOPRIGHT', self)
   
   -- Register it with oUF
   self.MasterLooter = MasterLooter

 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.
