* - Vector<double> stores value for the given identifier in each cell.
* To access the value, use cell_data[name_field][cell->active_cell_index()].
*
- * For example, if the vtk mesh contains field data 'Density' defined at the
- * cells, cell_data['Density'][0] would be the density defined at cell ID '0',
- * which corresponds to index 0 of the vector. The length of the vector in
- * cell_data['Density'] would equal the number of elements in the coarse
- * mesh.
+ * For example, if the vtk mesh contains field data "Density" defined on
+ * cells, then `cell_data["Density"][0]` provides the density defined at cell
+ * ID '0', which corresponds to index 0 of the vector. The length of the
+ * vector in `cell_data["Density"]` equals the number of elements in the
+ * coarse mesh.
