changed moments in newton optimizer to const( safety reasons )
    .parallelized newton multicell optimizer.removed<iostream> from several files.Added datagenerator mode to GaussLegendreQuadrature. Parallelized
    datagenerator. Datagen works now. added safer destructor for datagen. computed initial condition for linesources with monomials

quadrature overhaul. Fixed coordinate trafo, fixed reduced accuracy issue for lookup tables, fixed integration on sphere

encapsulated momentBasisIndexing in SphericalBasisClass. Added error catches for PN solver with wrong basis choice. Adapted MN Solver to monomial basis (constructor, output, solver. Scatterkernel works only for isotropic (not tested)). Adapted setup of initial conditions to changed basis. More encapsulating in solverbase. Shifting PrepareVolumeoutput from constructor to solverPreprocessing.
