Detailed Description

This class serves to duplicate the functionality of the MultisegmentWell A MultisegmentWell uses C, D and B and performs y -= (C^T * (D^-1 * (B*x))) B and C are matrices, with M rows and N columns, where N is the size of the matrix. They contain blocks of MultisegmentWell::numEq by MultisegmentWell::numWellEq. D is a MxM matrix, the square blocks have size MultisegmentWell::numWellEq. B*x and D*B*x are a vector with M*numWellEq doubles C*D*B*x is a vector with N*numEq doubles.
