StructureMerge Viewers

###### Identifier:

org.eclipse.compare.structureMergeViewers

###### Description:

This extension point allows a plug-in to register compare/merge viewers for structural content types. The viewer is expected to extend `org.eclipse.jface.viewers.Viewer`. However, since viewers don't have a default constructor, the extension point must implement the factory interface for viewers `org.eclipse.compare.IViewerCreator`.
