% given an arbitrary number of directories, concatenate the output
% structs of dir('*.hdf5'). The "names" fields are modified to
% contain full absolute paths to the files
%
% INPUT:
%  directory paths as strings
%
% OUTPUT:
%  flist a matlab struc similar to output of dir, but with absolute
%        paths and outputs of all input directories concatenated.
