/**
* Parse speaking URL and translate it to parameters understood by TYPO3
* Function is called from tslib_fe
* The overall format of a speaking URL is these five parts [TYPO3_SITE_URL] / [pre-var] / [page-identification] / [post-vars] / [file.ext]
* - "TYPO3_SITE_URL" is fixed value from the environment,
* - "pre-var" is any number of segments separated by "/" mapping to GETvars AND with a known lenght,
* - "page-identification" identifies the page id in TYPO3 possibly with multiple segments separated by "/" BUT with an UNKNOWN length,
* - "post-vars" is sets of segments offering the same features as "pre-var"
* - "file.ext" is any filename that might apply
*
* @param array $params Params for hook
* @return void Setting internal variables.
