> We assume the input itemsets are multi-item in PrefixSpan, e.g., (ab)(cd). In 
> some use cases, all itemsets are single-item, e.g., abcd. In this case, our 
> implementation has overhead remembering the boundaries between itemsets. We 
> could detect it and put specialized implementation for this use case.
