 Implementation of main solver for linear systems

 Computes the diagonal matrices in the augmented system from the current set of variables
void Solve(TQpDataBase *prob,TQpVar *vars,TQpResidual *res,TQpVar *step)
 Solves the system for a given set of residuals. Assembles the right-hand side appropriate
 to the matrix factored in factor, solves the system using the factorization produced there,
 partitions the solution vector into step components, then recovers the step components
 eliminated during the block elimination that produced the augmented system form .
void SolveXYZS(TVectorD &stepx,TVectorD &stepy, TVectorD &stepz,TVectorD &steps, TVectorD & /* ztemp */, TQpDataBase * /* prob */ )
