This package provides an implementation of projection documents. Projection is a specific master/slave mapping. Non-overlapping fragments if a master document form the segments of a slave document. The slave document is completely built out of segments, i.e. there are no gaps between two neighboring segments. The segments have exactly the same sequence in which they apprear as fragments in the master document.
ProjectionDocument is custom 
  IDocument implementation that 
  uses a ProjectionTextStore. The 
  content of the ProjectionDocument 
  is defined by the ProjectionMapping. 
  The ProjectionDocumentManager 
  manages the life cycle of ProjectionDocuments 
  and their relation to their master documents.
