    TextStatistics Project
    https://github.com/DaveChild/Text-Statistics

    Released under New BSD license
    http://www.opensource.org/licenses/bsd-license.php

    Calculates following readability scores (formulae can be found in Wikipedia):
      * Flesch Kincaid Reading Ease
      * Flesch Kincaid Grade Level
      * Gunning Fog Score
      * Coleman Liau Index
      * SMOG Index
      * Automated Reability Index
      * Dale-Chall Readability Score
      * Spache Readability Score

    Will also give:
      * String length
      * Letter count
      * Syllable count
      * Sentence count
      * Average words per sentence
      * Average syllables per word

    Sample Code
    ----------------

    $text = 'The quick brown fox jumped over the lazy dog.';
    echo 'Flesch-Kincaid Reading Ease: ' . $statistics->flesch_kincaid_reading_ease($text);
