/**
 * @brief DumpLocalGranVTK class
 *        write gran bond data to vtk files.
 *
 * Similar to the DumpCustomVTK class but uses the vtk library to write data to vtk simple
 * legacy or xml format depending on the filename extension specified. (Since this
 * conflicts with the way binary output is specified, dump_modify allows to set the
 * binary flag for this dump command explicitly).
 * In contrast to DumpCustom 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.)
 * This dump command does not support compressed files, buffering or custom format strings,
 * multiproc is only supported by the xml formats, multifile option has to be used.
