/**
* Inserts the URL of an application page
*
* This plug-in allows you to generate a module location URL. It uses any URL rewriting
* mechanism and rules you'll have configured for the system.
*
* To ensure this can be as optimized as possible, it accepts 2 modes of operation:
*
* <b>Static address generation</b>:<br>
* This is the default mode and fastest mode. When used, the URL is generated during
* the template compilation, and statically written in the compiled template file.
* To use it, you just need to provide a location in a format XOOPS understands.
*
* <code>
* // Generate an URL using a physical path
* ([xoAppUrl modules/something/yourpage.php])
* // Generate an URL using a module+location identifier (2.3+)
* ([xoAppUrl mod_xoops_Identification#logout])
* </code>
*
* <b>Dynamic address generation</b>:<br>
* The is the slowest mode, and its use should be prevented unless necessary. Here,
* the URL is generated dynamically each time the template is displayed, thus allowing
* you to use the value of a template variable in the location string. To use it, you
* must surround your location with double-quotes ("), and use the
* {@link http://smarty.php.net/manual/en/language.syntax.quotes.php Smarty quoted strings}
* syntax to insert variables values.
*
* <code>
* // Use the value of the $sortby template variable in the URL
* ([xoAppUrl "modules/something/yourpage.php?order=`$sortby`"])
* </code>
* @param $argStr
* @param $compiler
* @return string
