| 31 |  |  | \brief Bond class | 
| 32 |  |  |  | 
| 33 |  |  | The OBBond class is straightforward in its data access and | 
| 34 |  |  | modification methods. OBBonds store pointers to the atoms on each end | 
| 35 |  |  | of the bond. In storing pointers to atoms instead of integer indices, | 
| 36 |  |  | the necessity of having to reorder bonds when atoms are shuffled, | 
| 37 |  |  | added, or delete is obviated. |
