51 > * @brief As one of the heavy weight class of OOPSE, SimInfo
52 > * One of the major changes in SimInfo class is the data struct. It only maintains a list of molecules.
53 > * And the Molecule class will maintain all of the concrete objects (atoms, bond, bend, torsions, rigid bodies,
54 > * cutoff groups, constrains).
55 > * Another major change is the index. No matter single version or parallel version,  atoms and
56 > * rigid bodies have both global index and local index. Local index is not important to molecule as well as
57 > * cutoff group.
