```
public interface ISequenceSubRule<ILigand>
extends Comparator<ILigand>
```
Sequence sub rule used in the CIP method to decide which of the two ligands takes precedence [Cahn, R.S. et. al.. Angew. Chem. Int. Ed.. 1966. 5]. A list ordered based on these rules will be sorted from low to high precedence.

  - compare
```
int compare(ILigand ligand1,
            ILigand ligand2)
```
    Compares two ligands according to the particular sequence sub rule. It returns 1 if ligand1 takes precedence over ligand2, -1 if ligand2 takes precedence over ligand1, and 0 if they are equal.
    
    Specified by:
    
    compare in interface Comparator<ILigand>
    
    Parameters:
    
    ligand1 - the first of the two ligands to compare
    
    ligand2 - the second of the two ligands to compare
    
    Returns:
    
    1 if ligand1 is of higher precedence than ligand2, -1 if ligand2 is of higher precedence than ligan1, and 0 if they have equal precedence
