Seq (core 3.2 API)

java.lang.Object
- fj.data.Seq<A>

```
public final class Seq<A>
extends java.lang.Object
```
Provides an immutable finite sequence, implemented as a finger tree. This structure gives O(1) access to the head and tail, as well as O(log n) random access and concatenation of sequences.

`Seq<A>`	`cons(A a)` Inserts the given element at the front of this sequence.
`static <A> Seq<A>`	`empty()` The empty sequence.
`A`	`index(int i)` Returns the element at the given index.
`boolean`	`isEmpty()` Checks if this is the empty sequence.
`int`	`length()` Returns the number of elements in this sequence.

    Returns:
    A new sequence with the given element at the end.
  - append
```
public Seq<A> append(Seq<A> as)
```
    Appends the given sequence to this sequence.
    
    Parameters:
    as - A sequence to append to this one.
