Type Parameters:

Value_ - The type of value in the sequence

Difference_ - The type of difference between values in the sequence
```
public interface Sequence<Value_,Difference_ extends Comparable<Difference_>>
```
A Sequence is a series of consecutive values. For instance, the list [1,2,4,5,6,10] has three sequences: [1,2], [4,5,6], and [10].
