/**
* Please note that the methods offered in this service are the same as Data
* Laboratory nodes manipulators. It is possible to reuse actions
* implementations by adding both ServiceProvider annotations.
*
* Interface from providing graph context menu items as services.
*
* All context menu items are able to:
*
* - Execute an action
* - Provide a name, type and order of appearance (position in group of its
* type)
* - Indicate whether they have to be available (appear in the context menu)
* or not
* - Indicate whether they have to be executable (enabled in the context menu)
* or not
* - Provide and icon or not
*
*
* Used for different manipulators such as NodesManipulator, EdgesManipulator
* and GeneralActionsManipulator.
*
* The only methods that are called before setting up an item with the data are
* getSubItems, getType and getPosition.
* This way, the other methods behaviour can depend on the data that has been
* setup before
*
* getSubItems will be called before and after setup. Take care when the
* nodes are null!
*
* To provide a context menu item, a class has to implement this interface and
* have a @ServiceProvider annotation
