Callbacks

Every collection can have an optional callback node. In this node there are five functions:

create	Is called when an element was successfully added to the collection
read	Is called when the collection was successfully queried about an element
update	Is called when an element in the collection was successfully updated
delete	Is called when an element was successfully removed from the collection
resize	Is called when the collection was full and successfully resized

Check the documentation for each collection to see which functions call which callbacks.
