    @brief Simple ETA test to compute a block matrix associated to the Stokes problem

    @author L. Pasquale <luca.pasquale@mail.polimi.it>

    This test computes the matrix and teh RHS vector associated to the Stokes problem: \n
    \f$
        \left\{\begin{array}{ll}
        - \delta u + \nabla p = f \\
        \nabla \cdot u=0
    \end{array}\right. \mathrm{in} (-1,1)\mathrm{x}(-1,1)
    \f$ \n
    with \f$u\f$ a scalar field approximated with P2 functions and p approximated with P1 \n
