Connects the given function dynamically with the event handler, id and

This is an alternative to the use of static event tables. It is more
flexible as it allows to connect events generated by some object to an
event handler defined in a different object of a different class (which
is impossible to do directly with the event tables -- the events can be
only handled in another object if they are propagated upwards to it).
Do make sure to specify the correct @a eventSink when connecting to an
event of a different object.
See @ref overview_eventhandling_connect for more detailed explanation
of this function and the @ref page_samples_event sample for usage
examples.
This specific overload allows you to connect an event handler to a @e range
of @e source IDs.
