introduced new dummy module "libs" for inclusion of further library sources. contains kdtree2 and Lib_VTK_IO at and is enabled for the spectral solver only at the moment

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.

10e50bf41d
improved accuracy of "accumulated shear": now added as a state variable, which facilitates integration (dotstate=shearrate); needs absolute tolerance value for state integration in material.config

b8f8d66f82
total density used in backstress calculation now based on average of neighborhood
