/**
  * \defgroup IterativeLinearSolvers_Module Iterative Solvers module
  * This module aims to provide various iterative linear and non linear solver algorithms.
  * It currently provides:
  *  - a constrained conjugate gradient
  *  - a Householder GMRES implementation
  *  - an IDR(s) implementation
  *  - a BiCGSTAB(L) implementation
  *  - a DGMRES implementation
  *  - a MINRES implementation
  *  - a IDRSTABL implementation
  *
  * Choosing the best solver for solving \c A \c x = \c b depends a lot on the preconditioner chosen as well as the properties of \c A. The following flowchart might help you.
