org.eclipse.ui.internal.texteditor.quickdiff.DocumentLineDiffer
Standard implementation of ILineDiffer as an incremental diff engine. A DocumentLineDiffer can be initialized to some start state. Once connected to a IDocument and a reference document has been set, changes reported via the IDocumentListener interface will be tracked and the incremental diff updated.
The diff state can be queried using the ILineDiffer interface.

Since diff information is model information attached to a document, this class implements IAnnotationModel and can be attached to IAnnotationModelExtensions.

This class is not supposed to be subclassed.
