    PLANT solves a two-dimensional steady diffusion problem  with
    space-dependent  source and boundary conditions.
    It can be tested against exact solution  fields.

    Governing equation:
    d(dT/dX)/dX + d(dT/dX)/dX +  S(X,Y)  =  0
    S(X,Y)  =  2.sinX.sinY
    Boundary  conditions:
    Y = 0 ;  T = 0
    Y = 1 ;  T = sin1.sinX
    X = 0 ;  T = 0
    X = 1 ;  T = sin1.sinY
    Exact solution:
    T(X,Y) = sinX.sinY
