+$symb is symb for resource, $uname and $udom are for current user (required).
+$caller is optional (can be "submission", if routine is called when storing
+an upoaded file when "Submit Answer" button was pressed).
+
+Returns array containing $path and $multiresp. 
+$path is path in portfolio.  $multiresp is 1 if this resource contains more
