1 The DRelAlgebra

This algebra provides operators to make it easier for the user to distribute
relations to many worker systems. The algebra proviedes also operators to 
formulate queries to the distributed relations. A distributed relation is
represented by the type DRel. This algebra mainly uses the Distributed2Algebra.
