# Spiral Matrix

Given the size, return a square matrix of numbers in spiral order.

The matrix should be filled with natural numbers, starting from 1
in the top-left corner, increasing in an inward, clockwise spiral order,
like these examples:

###### Spiral matrix of size 3

```plain
1 2 3
8 9 4
7 6 5
```

###### Spiral matrix of size 4

```plain
 1  2  3 4
12 13 14 5
11 16 15 6
10  9  8 7
```


## Getting Started

For installation and learning resources, refer to the
[exercism help page](http://exercism.io/languages/haskell).

## Running the tests

To run the test suite, execute the following command:

```bash
stack test
```

#### If you get an error message like this...

```
No .cabal file found in directory
```

You are probably running an old stack version and need
to upgrade it.

#### Otherwise, if you get an error message like this...

```
No compiler found, expected minor version match with...
Try running "stack setup" to install the correct GHC...
```

Just do as it says and it will download and install
the correct compiler version:

```bash
stack setup
```

## Running *GHCi*

If you want to play with your solution in GHCi, just run the command:

```bash
stack ghci
```
