"""
This script checks periodically if the new grades are online within the FHWS-Studentenportal. If three login attempts in a row failed the script exits.
It depends on selenium with phantomjs-webdriver. To use this script both must be installed!
Tested with python 2.7 and windows - if you want to use in on linux you have to remove winsound.
