00030 // DistributedSparseGenColLinSOE is a subclass of LinearSOE. It uses the sparse column
00031 // storage scheme. It collects all contributions from the matrices and assembles them onto 
00032 // P0 (not really a distributed SOE .. but until i get a solver that will work with a distributed
00033 // col storage scheme this is what will have to stick with).
