\brief
LinkedEvent is an Event subclass that provides a mechanism to link or chain
Events together, such that when a specified target event is fired, then
this event will additionally fire in response.
\par
The expected use of this mechanism is for container or compound widgets to
be able to expose events of component widgets without needing to provide
repetetive boilerplate event forwarding code, and also for scenarios where
code is not typically provided (i.e. data based skinning scenarios).

\brief
Add a link target for this event. A link target is an event that
will trigger this event.

Reference to an Event that, when fired, will additionally cause
this Event to fire.
\note
Once an event link is established it can not currently be broken
without destroying this Event completely.
