// Description: This file contains the class definition for DistributedSparseGenColLinSOE
// DistributedSparseGenColLinSOE is a subclass of LinearSOE. It uses the sparse column
// storage scheme. It collects all contributions from the matrices and assembles them onto 
// P0 (not really a distributed SOE .. but until i get a solver that will work with a distributed
// col storage scheme this is what will have to stick with).
