%------------------------------------------------------------------------
% function [ListDevices,ListRecords,ListXml,List]=dir_scan(CurrentPath,ListExperiments,ListDevices_in,ListRecords_in)
%
% 
% OUTPUT:
%  ListDevices: list of Devices 
%  ListRecords: list of records
%  ListXml: list of xml file names
%  List: structure representing the tree structure
%
% INPUT:
%  CurrentPath: full name (including path) to the input campaign (or subcampaign), we assume that
%          data are organised as (sub)campaign/Experiment/Device/(Record/)/file .xml
%  ListExperiments: list of experiments to scan (cell of names)
%  ListDevices_in: list of devices to scan (cell of names)
%  ListRecords_in: list of records to scan (cell of names)
