When a wizard node comes into existence, its wizard may or may
not have been created yet;
be used to determine which. A node may be asked for its wizard
getWizard, which will force it to be created
if required. Once the client is done with a wizard node, its
disposemethod must be called to free up the wizard;
once disposes, the node should no longer be used.
This interface should be implemented by clients wishing to support this kind of wizard placeholder in a wizard selection page.
