Detailed Description

Provides an exploded view of the detector (tree-view)

DDExpandedView provides a tree-walker (iterator) for the expanded view of the detector description. Further it provides a registration mechanism for call-backs whenever a node in the expanded view becomes current and fullfills the user-defined predicate.

FIXME: DDExpandedView: in the Prototype just one class - FIXME: later seperation of interface & implementation! Taking a DDCompactView the DDExpandedView expands the compact-view into a detector tree. One instance of DDExpandedView corresponds to one node in the tree. It is the 'current' node. By using tree navigation ( next(), nextSibling(), parent(), firstChild() ) the DDExpandedView represents the new corresponding node.
