    This SIS class can be used for testing the SIS functions. It can be taken into use
    by adding the following to settings.py:

    SIS_PLUGIN_MODULE = 'course.sis_test'
    SIS_PLUGIN_CLASS = 'SisTest'

    By using optional SIS_TEST_FILE setting, one can specify a file from which the SIS
    configuration is read, overriding the default setup above.
