 An optional Closure may be specified and will work as a filter, if it returns true the property
 will trigger an event (if the value indeed changed), otherwise it won't. The Closure may receive
 1 or 2 parameters, the single one being the value, the other one both the key and value, for
 example:
 
 // skip all properties whose value is a closure
 def map = new ObservableList( {!(it instanceof Closure)} )
 // skip all properties whose name matches a regex
 def map = new ObservableList( { name, value -> !(name =˜ /[A-Z+]/) } )
 The current implementation will trigger specialized events in the following scenarios, you need
 not register a different listener as those events extend from PropertyChangeEvent
 - ObservableList.ElementAddedEvent - a new element is added to the list
- ObservableList.ElementRemovedEvent - an element is removed from the list
- ObservableList.ElementUpdatedEvent - an element changes value (same as regular
 PropertyChangeEvent)
- ObservableList.ElementClearedEvent - all elements have been removed from the list
- ObservableList.MultiElementAddedEvent - triggered by calling list.addAll()
- ObservableList.MultiElementRemovedEvent - triggered by calling
 list.removeAll()/list.retainAll()
 
 Bound properties
  
 - content - read-only.
- size - read-only.
