Description: Barrels, python module for handle many small files
        ==================================================
        
        Barrels sticks files into barrels, the barrels look like csv file (tab
        seperated) the meta information is readable, the content of each files
        is gziped and b64 encoded.
        
        .. code:: Python
        
            import barrels
            # new barrel
            b = barrels.Barrel("items/demo")
            # store data in a barrel
            b.add(name="filename or key", data="this is the content of the file")
        
            # get files from barrel, using itterators
            print("Content of file - single ")
            for meta, content in b.filter():
                print(meta)
