This is mainly for when a file, or folder is created from a torrent download to determine what 'type' it is.
The currently the types are 'movie', 'audio'. More can be added.
var info = require('media-folder-info');
info('/home/you/downloads/folder', function(err, data){
if (err) return console.log(err);
console.log(data.type); // 'video', 'audio',
console.log(data.files); // the main file(s), eg '/home/you/downloads/folder/movie-1999.avi'
})
