/**
* Return the special URI array or just one special URI args array.
*
* /application/config/ionize.php defines the special URIs and the corresponding user's chosen URIs :
* $config['special_uri'] = array(
* 'user_chosen_uri' => 'internal_uri'
* );
*
* This method checks the URL segments, looks for "user_chosen_uri" and returns one array containing,
* for each "internal_uri", the asked args.
* Example of return :
* array(
* 'internal_uri' => array(
* 0 => 'foo'
* 1 => 5
* )
* );
*
* @param null|string If set, return the args array of the given "internal_uri"
*
* @return array|null
*
