Detailed Description

This class handles the access to a distributed matrix (or array).

A number of nodes load the parts and these nodes should respond to access requests. On these nodes the function StartEventLoop() should be called. Other nodes can access parts on other nodes by calling GetColumn() or GetDiagonal(). Because this class is created for use by the SVM these are the only accessors currently implemented.

Each class knows on what node a part is so communication can be kept to a minimum.
