-/**
- * Implementation of {@link IStructuredContentProvider} and {@link ILabelProvider} that 
- * maintains a collection (Map, actually) of {@link ItemContentProvider} 
- * delegates that perform the function of providing content and label information
- * for each represented item
- * 
- * NB: This class, if used as a label provider *MUST* be used as a content provider
- * for the same viewer.  It may be used as a content provider with a different
- * label provider, however.
- * 
- * Provisional API: This class is part of an interim API that is still
- * under development and expected to change significantly before reaching
- * stability. It is available at this early stage to solicit feedback from
- * pioneering adopters on the understanding that any code that uses this API
- * will almost certainly be broken (repeatedly) as the API evolves.
