# Sublist

Given two lists determine if the first list is contained within the second
list, if the second list is contained within the first list, if both lists are
contained within each other or if none of these are true.

Specifically, a list A is a sublist of list B if by dropping 0 or more elements
from the front of B and 0 or more elements from the back of B you get a list
that's completely equal to A.

Examples:

 * A = [1, 2, 3], B = [1, 2, 3, 4, 5], A is a sublist of B
 * A = [3, 4, 5], B = [1, 2, 3, 4, 5], A is a sublist of B
 * A = [3, 4], B = [1, 2, 3, 4, 5], A is a sublist of B
 * A = [1, 2, 3], B = [1, 2, 3], A is equal to B
 * A = [1, 2, 3, 4, 5], B = [2, 3, 4], A is a superlist of B
 * A = [1, 2, 4], B = [1, 2, 3, 4, 5], A is not a superlist of, sublist of or equal to B

## Elm Installation

Refer to the [Exercism help page](http://exercism.io/languages/elm) for Elm
installation and learning resources.

## Writing the Code

The first time you start an exercise, you'll need to ensure you have the
appropriate dependencies installed.

```bash
$ npm install
```

Execute the tests with:

```bash
$ npm test
```

Automatically run tests again when you save changes:

```bash
$ npm run watch
```

As you work your way through the test suite, be sure to remove the `skip <|`
calls from each test until you get them all passing!


## Submitting Incomplete Solutions
It's possible to submit an incomplete solution so you can see how others have completed the exercise.
