### returns the rest of a pair or sequence

Usage:

`(cdr seq)`

This function will return the portion of a pair or sequence that excludes its first element. For sequences, this will be the remainder of the sequence. For cons pairs, this will be the cdr portion.

#### An Example

```
(define x '(99 64 32 48))
(cdr x) ;; will return (64, 32, 48)
(define y (100 . 200))
(cdr y) ;; will return 200
```
