%'read_multimadoc': read a set of Imadoc files for different file series and compare their timing

% OUTPUT:

% NbSlice_calib: nbre of slices detected in the geometric calibration data
% Time(iview,i,j): matrix of times, iview =index of the series, i,j=file indices within the series
%                if the time is not consistent in all series, the time from the first series is chosen
% warnmsg: warning message, ='' if  OK
%
% INPUT:
% RootPath,SubDir,RootFile,FileExt: cell arrays characterizing the input file series
% i1_series,i2_series,j1_series,j2_series: cell arrays of file index arrays, as given by the fct uvmat/get_file_series
