78     * @class SimInfo SimInfo.hpp "brains/SimInfo.hpp"
79 <   * @brief As one of the heavy weight class of OOPSE, SimInfo
80 <   * One of the major changes in SimInfo class is the data struct. It only maintains a list of molecules.
81 <   * And the Molecule class will maintain all of the concrete objects (atoms, bond, bend, torsions, rigid bodies,
82 <   * cutoff groups, constrains).
83 <   * Another major change is the index. No matter single version or parallel version,  atoms and
84 <   * rigid bodies have both global index and local index. Local index is not important to molecule as well as
85 <   * cutoff group.
