/**
 * This class implements word-hyphenation
 *
 * Word-hyphenation is implemented on the basis of the algorithms developed by
 * Franklin Mark Liang for LaTeX as described in his dissertation at the department
 * of computer science at stanford university.
 *
 * The idea to this package came from Mathias Nater <[email protected]> who
 * implemented this word-hyphenation-algorithm for javascript.
 *
 * After Implementing that algorithm for the first Hyphenator-Version I stumbled
 * over the Informations of LÁSZLÓ NÉMETH from OpenOffice.org.
 *
 * That brought me to change three things for the next Version of the
 * Hyphenator.
 * <ol>
 * <li>Use the Dictionary files from OpenOffice.org instead of the ones directly
 * from Tex because the OOo-Files are already stripped of the unnecessary
 * Informations</li>
 * <li>Add the possibility to use non-standard hyphenations</li>
 * <li>Add the possibility to add better word-tokenising</li>
 * </ol>
 *
 * Beside those changes there are some other changes between the first and the
 * second version of the Hyphenator.
 *
 * So Version 2 of the Hyphenator<ul>
 * <li>requires PHP5.3 as it uses namespaces.</li>
 * <li>aims to 100% Code-Coverage via Unit-Tests</li>
 * <li>removes some unnecessary options</li>
 * <li>is completely rewritten from scratch</li>
 * </ul>
 *
 * So here is the smalest example for the usage of the class:
 * <code>
 * &lt;?php
 * use \Org\Heigl\Hyphenator as h;
 * // Create a hyphenator-instance based on a given config-file
 * $hyphenator = h\Hyphenator::factory('/path/to/the/config/file.properties');
 *
 * // And hyphenate a given string
 * $hyphenatedText = $hyphenator->hyphenate($string);
 * </code>
 * Registering the autoloader is essential before the first call to the
 * Hyphenator
 * <code language="php">
 * &lt;?php
 * require_once '/path/to/Org/Heigl/Hyphenator/Hyphenator.php';
 * spl_autoload_register('\Org\Heigl\Hyphenator\Hyphenator::__autoload');
 * </code>
 * Of course the Hyphenator can be adapted to the most requirements via an
 * Options-Object. And the tokenisation in this small example uses the simple
 * WhiteSpace-Tokenizer. Other more complex Tokenizers are available.
 *
 * Examples for those can be found at http://github.com/heiglandreas/Hyphenator

62		* <ol>
63		* <li>Use the Dictionary files from OpenOffice.org instead of the ones directly
64		* from Tex because the OOo-Files are already stripped of the unnecessary
65		* Informations</li>
66		* <li>Add the possibility to use non-standard hyphenations</li>
67		* <li>Add the possibility to add better word-tokenising</li>
68		* </ol>
69		*
70		* Beside those changes there are some other changes between the first and the
71		* second version of the Hyphenator.
72		*
73		* So Version 2 of the Hyphenator<ul>
74		* <li>requires PHP5.3 as it uses namespaces.</li>
75		* <li>aims to 100% Code-Coverage via Unit-Tests</li>
76		* <li>removes some unnecessary options</li>
77		* <li>is completely rewritten from scratch</li>
78		* </ul>
79		*
80		* So here is the smalest example for the usage of the class:
81		* <code>
82		* <?php
83		* use \Org\Heigl\Hyphenator as h;
84		* // Create a hyphenator-instance based on a given config-file
85		* $hyphenator = h\Hyphenator::factory('/path/to/the/config/file.properties');
86		*
87		* // And hyphenate a given string
88		* $hyphenatedText = $hyphenator->hyphenate($string);
89		* </code>
90		* Registering the autoloader is essential before the first call to the
91		* Hyphenator
92		* <code language="php">
93		* <?php
94		* require_once '/path/to/Org/Heigl/Hyphenator/Hyphenator.php';
95		* spl_autoload_register('\Org\Heigl\Hyphenator\Hyphenator::__autoload');
96		* </code>
97		* Of course the Hyphenator can be adapted to the most requirements via an
98		* Options-Object. And the tokenisation in this small example uses the simple
99		* WhiteSpace-Tokenizer. Other more complex Tokenizers are available.
100		*
101		* Examples for those can be found at http://github.com/heiglandreas/Hyphenator
