--[[ Element: Leader Icon
Toggles visibility based on the units leader status.
Widget
Leader - Any UI widget.
Notes
The default leader 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 Leader = self:CreateTexture(nil, "OVERLAY")
Leader:SetSize(16, 16)
Leader:SetPoint("BOTTOM", self, "TOP")
-- Register it with oUF
self.Leader = Leadera
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.
