* @brief DumpLocalGran class
* write gran bond data to vtk arrays.
*
* Similar to the DumpParticle class but uses the vtk library to copy data to vtk data types
* In contrast to the DumpParticle class the attributes to be packed are stored in a std::map
* to avoid duplicate entries and enforce correct ordering of vector components (except
* for computes and fixes - these have to be given in the right order in the input script).
* (Note: std::map elements are sorted by their keys.)
