This is an abstract class for computing user-defined integral-based functionals of a solution on the mesh. The user needs to define GetIntegrand() in the concrete class, and this class can then be used to compute the integral of f(x,u,grad_u) over the mesh, where x is position, u is the solution at x (possibly with multiple components, for which PROBLEM_DIM>1), grad_u the gradient of u and f the integrand as defined in the concrete class.
Note linear basis functions are the default, but that the functional may be non-polynomial. The order of integration used is the highest degree available (3rd order Gaussian quadrature)

Note that, in parallel, this method uses a collective reduction step and should therefore always be called collectively.
