========
extract relevant keywords from a given text
How to use it
-------------
In order to use the class, you must instance a `Config` object.
```php
getKeywords($some_long_text);
var_dump($keywords);
```
It is possible to get better results by adding few information about the language (`stopword` list, `stemmer` with `pecl install stem`).
```php
addListener(new Stopword);
$textrank = new TextRank($config);
$keywords = $textrank->getKeywords($some_long_text);
var_dump($keywords);
```
By doing this it will detect the language of the text and will remove common words (from the stopword list). If `ext-stem` is available the results will be even better.
Summarize large texts
---------------------
This class is also capable of summarizing long texts
```php
$config = new \crodas\TextRank\Config;
$config->addListener(new \crodas\TextRank\Stopword);
$analizer = new \crodas\TextRank\Summary($config);
$summary = $analizer->getSummary($text);
```
`$summary` is at most 5% of the sentences of the text.
