title: Order the result for listing child in pydrive
body: <pre><code>from pydrive.auth import GoogleAuth
  from pydrive.drive import GoogleDrive
  gauth = GoogleAuth()
  gauth.LocalWebserverAuth()
  drive = GoogleDrive(gauth)
  def get_children(root_folder_id):
      str = &quot;\'&quot; + root_folder_id + &quot;\'&quot; + &quot; in parents and trashed=false&quot;
      file_list = drive.ListFile({'q': str}).GetList()
      return file_list
  </code></pre>
  <p>could we force the file list to be ordered in someway (alphabetical, last date modified, etc)</p>
