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

For level zero it's assumed, that both ansatz-functions do exist: 0,0 and 0,1 If one is missing this code might produce some bad errors (segmentation fault, wrong calculation result) So please assure that both functions do exist!

On level zero the getfixDirechletBoundaries of the storage object evaluated

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'
