@show: Slot for #IndicateIndicator::show.
@user_display: Slot for #IndicateIndicator::user-display.
@modified: Slot for #IndicateIndicator::modified.
@get_type: Returns a constant string for the type of this indicator.
Typically gets overridden by subclasses and defines the type of
the indicator.
@set_property: Called when #indicate_indicator_set_property is called
and should set the value. While typically it is overridden by
subclasses they usually handle special properties themselves and
then call the superclass for storage.
@get_property: Called when #indicate_indicator_get_property is called
and should return the value requested. Many times this is left alone.
@list_properties: Called when #indicate_indicator_list_properties is called
and returns a list of the properties available. Again this can be
overridden by subclasses to handle special properties.
