//Function:    sefalize 
//Description: Intended for converting one-argument dynamic URLs to
//             Search-Engine-Friendly URLs. Unsuitable for scripts
//             which are passed more than one argument. 
//Arguments:   $url         - the regex pattern to search for 
//             $replacement - the regex pattern to replace
//             $string      - the string we are smarty-output-filtering

//Function:    niceify 
//Description: a scaled-down version of "sefalize". Intended just for renaming

//             $replacement - the "nice" name to give the script
//             $string      - the string we are smarty-output-filtering
