Marginalizes (Density) Functions.

Parameters

alpha	Coefficient vector for current grid
mg	Referenz of grid pointer
malpha	Coefficient vector for new grid (mg). Will be resized.
mdim	Marginalize in dimension mdim

Note: Because of adaptively refined sparse grids, we cannot simply generate a regular grid. Thus, we need to add point after point to the new grid mg

Compute coefficients for marginalized density Each coefficient has to be weighted with the integral of the basis functions in direction mdim

Attention: The integral of one basis functions changes for if another type of basis is used!
