This operations performs the calculation of down in the direction of dimension dim

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 up operation
index	a iterator object of the grid
dim	current fixed dimension of the 'execution direction'
