Class that implements the hierarchisation on a mod linear sparse grid.
Therefore the ()operator has to be implement in order to use the sweep algorithm for the grid traversal

Implements operator() needed by the sweep class during the grid traversal.
This function is applied to the whole grid.
source | this DataVector holds the node base coefficients of the function that should be applied to the sparse grid |
result | this DataVector holds the linear base coefficients of the sparse grid's ansatz-functions |
index | a iterator object of the grid |
dim | current fixed dimension of the 'execution direction' |
