bml_info_file

 BML_INFO_FILE returns table with OS info of each file in a folder

 Use as
   tab = bml_info_file(cfg);

 The first argument cfg is a configuration structure, which can contain
 the following field:
 cfg.path - string: path to the folder containing the files. Defauts to '.'
 cfg.pattern - string: file name pattern (eg '*.mat')
 cfg.regexp - string: regular expression to filter files
 cfg.filetype - string: variable added to info table

 Returns a matlab 'table' with the folloing variables:
   name - cell array of char: filename
   folder - cell array of char: path
   date - cell array of char: data of file modification 
   bytes - double: Size of the file in bytes
   isdir - logical: 1 if name is a folder; 0 if name is a file
   datenum - double: Modification date as serial date number.
