    idGroup - sequence order for the matrix
    
    tree -
  - getSplits
```
public static SplitSystem getSplits(Tree tree)
```
    creates a split system from a tree (using tree-induced order of sequences)
    
    Parameters:
    
    tree -
  - getSplit
```
public static void getSplit(IdGroup idGroup,
                            Node internalNode,
                            boolean[] split)
```
    get split for branch associated with internal node
    
    Parameters:
    
    idGroup - order of labels
    
    internalNode - Node
    
    boolean - [] split
  - isSame
```
public static boolean isSame(boolean[] s1,
