  function getFileNames(path,callback){
    // Read a folder recursively looking for js files

    recursiveReadDir(path);

    // Recursor
    function recursiveReadDir(path){

      fs.readdir(path,function(err,x){
        base.__count--;
        for(var j = 0; j < x.length; j++){
          i = x[j];
          if(i.indexOf(".") < 0 && !err){
            recursiveReadDir(path + i + "/",callback);
          }
          else if (i.indexOf(".js") > 0){
            base.arr.push(path + i);
          }
        }
