+ Inputs: 3 required + 1 optional.
+ $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.

+ than one file upload item.  Callers of routine should append partid as a
+ subdirectory to $path in cases where $multiresp is 1.
