calculation of cellnode positions now available in python via damask.core
...
first call damask.core.mesh.mesh_init_postprocessing(meshfilename) to initialize all necessary mesh variables
then damask.core.mesh.mesh_build_cellnodes(nodes) calculates the cellnode positions for a given list of node positions
the meshfile that is needed for the init is created automatically by mesh_init in DAMASK

Major restructuring of mesh.f90 due to introduction of "cells". A cell is the volume (area in 2D elements) that surrounds an ip. It is described by up to 8 cell nodes and is used to calculate ip volume, area, and face normals. It can also be used to generate a mesh for e.g. paraview that contains ip output as cell centered data.

restructured AL solver to resemble polarization scheme and introduced alpha and beta parameters in numerics to determine what kind of solution you want. alpha = beta = 1 results in the AL scheme. alpha = beta = 2 results in the accelerated scheme. safe values are anything in between. changed the solver to use stress calculations on the campatible field which seems to result in faster convergence.

moved stiffness tensor calculation to lattice
...
introduced 'isotropic' and 'orthorhombic' lattice types to use corresponding symmetries in stiffness tensor. intended to be used with non-crystal plasticity models (j2, constitutive_none with isotropic, cubic or orthotropic elasticity).

divergence_correction for basic solver variants has now 3 possibilities:
...
0: uncorrected, slope per sidelength (physical dimension) e = res/dim
1: corrected by sidelength, slope per unitlength e = res/1
2: corrected such that distance between FPs e = 1
alway regarding the medium length of x,y,z direction
