+=item * &get_turnedin_filepath()
+
+Determines path in a user's portfolio file for storage of files uploaded
+to a specific essayresponse or dropbox item.
+
+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 $multiresp.
+$path is path in portfolio. $multiresp is 1 if this resource contains more
+than one file upload item. Callers of routine should append partid as a
+subdirectory to $path in cases where $multiresp is 1.
+
+Called by: homework/essayresponse.pm and homework/structuretags.pm
