/**
* Mod rewrite url stack class. Provides features to collect urls and to get the
* pretty path and names of categories/articles at one go.
*
* Main goal of this class is to collect urls and to get the urlpath and urlname
* of the related categories/articles at one go. This will reduce the queries
* against the database.
* Therefore the full advantage will be taken by rewriting the urls at codeoutput
* in front_content.php, where you will be able to collect all urls at once...
*
* Usage:
* <code>
* // get the instance
* $oMRUrlStack = ModRewriteUrlStack::getInstance();
*
* // add several urls to fill the stack
* $oMRUrlStack->add('front_content.php?idcat=123');
* $oMRUrlStack->add('front_content.php?idart=321');
* $oMRUrlStack->add('front_content.php?idcatart=213');
* $oMRUrlStack->add('front_content.php?idcatlang=213');
* $oMRUrlStack->add('front_content.php?idartlang=312');
*
* // now the first call will get the pretty path and names from database at one go
* $aPrettyParts = $oMRUrlStack->getPrettyUrlParts('front_content.php?idcat=123');
* echo $aPrettyParts['urlpath']; // something like 'Main-category-name/Category-name/Another-category-name/'
* echo $aPrettyParts['urlname']; // something like 'Name-of-an-article'
* </code>
