Markov Chain implementation.
You train it by giving it arrays of tokens. Then you can get the occurrences and probability of tokens after a given token.

Installation
------------

[](#installation)

You can install the package via composer:

```
$ composer require scripturadesign/markov
```

Usage
-----

[](#usage)

!!! Out of date, look in tests for now !!!

```
/* Create a new first order Markov Chain object */
$chain = new Chain(1);

/* Learn from arrays of tokens */
$chain->learn(['the', 'falcon', 'likes', 'the', 'snake']);

/* Get all the history of the training */
$chain->history();
// [
//     [
//         0 => [''],
//         1 => ['the'],
//         2 => ['falcon'],
//         3 => ['likes'],
//         4 => ['snake'],
//     ],
//     [
//         0 => ['the' => 1],
//         1 => ['falcon' => 1, 'snake' => 1],
//         2 => ['likes' => 1],
//         3 => ['the' => 1],
//         4 => ['' => 1],
//     ],
// ]
```

```
/* Create a new second order Markov Chain object */
$chain = new Chain(2);

/* Learn from arrays of tokens */
$chain->learn(['the', 'falcon', 'likes', 'the', 'snake']);

/* Get all the history of the training */
$chain->history();
// [
//     [
//         0 => ['', ''],
//         1 => ['', 'the'],
//         2 => ['the', 'falcon'],
//         3 => ['falcon', 'likes'],
//         4 => ['likes', 'the'],
//         5 => ['the', 'snake'],
//     ],
//     [
//         0 => ['the' => 1],
