This operations performs the calculation of down in the direction of dimension dim on a grid with Dirichlet 0 boundary conditions.

Parameters

source	sgpp::base::DataVector that contains the gridpoint's coefficients (values from the vector of the laplace operation)
result	sgpp::base::DataVector that contains the result of the down operation
index	a iterator object of the grid
dim	current fixed dimension of the 'execution direction'

Reimplemented in sgpp::pde::PhiPhiDownBBLinearBoundary.
