Added skeleton models for GradingSurveyGroup and Records. SurveyRecordGroup has been renamed to GradingRecord. GradingSurveyGroup will hold which Surveys should be linked. While the acompanying GradingRecords (with their reference to a GradingSurveyGroup) will hold the Records for each StudentProject that can take these Surveys.

# This module is DEPRECATED!
#
# You should no longer be using django.template_loader.

# Use django.template.loader instead.
