*
* @brief Class for handling the netcdf input file format for the minimal
* muLib configuration. In this configuration, a linear elastic problem
* is assumed, and the input file contains a per-pixel material label
* map of the two- or three-dimensional microstructure, a list of
* material properties in form of the elastic stiffness tensor as well
* as a map between labels and material properties. The input file
* format is netCDF3.
