27 Description
28  Determines processor-processor connection. After instantiation contains
29  on all processors the processor-processor connection table.
30 
31  *this[proci] gives the list of neighbouring processors.
32 
33  TODO: This does not currently correctly support multiple processor
34  patches connecting two processors.
