Description
    Laplace equation solver for a scalar quantity.

    \heading Solver details
    The solver is applicable to, e.g. for thermal diffusion in a solid.  The
    equation is given by:

    \f[
        \ddt{T}  = \div \left( D_T \grad T \right)
    \f]

    Where:
    \vartable
        T     | Scalar field which is solved for, e.g. temperature
        D_T   | Diffusion coefficient
    \endvartable

    \heading Required fields
    \plaintable
        T     | Scalar field which is solved for, e.g. temperature
    \endplaintable
