< | 
   * interactions (C++) and long range interactions (Fortran). If the | 
| 60 | 
< | 
   * Fortran side is not set up before the force calculation, call | 
| 61 | 
< | 
   * SimInfo's update function to settle it down. | 
| 69 | 
> | 
   * ForceManager is responsible for calculating both the short range | 
| 70 |

   * (bonded) interactions and long range (non-bonded) interactions. | 
| 71 | 
  | 
   * | 
| 72 | 
< | 
   * @note the reason we delay fortran side's setup is that some | 
| 73 |

   * applications (Dump2XYZ etc.) may not need force calculation, so why | 
| 74 | 
< | 
   * bother? | 
| 72 | 
> | 
   * @note the reason we delay some of the setup is that |
