--- A notification object.
--
-- This class creates individual notification objects that can be manipulated
-- to extend the default behavior.
--
-- This class doesn't define the actual widget, but is rather intended as a data
-- object to hold the properties. All examples assume the default widgets, but
-- the whole implementation can be replaced.

-- conflicting sources of "icons".

-- On the other hand, the vast majority of notifications don't multiple or
-- ambiguous sources of icons. This property will pick the first of the
-- following.
