rebuilt d4df7cbc06 Add scales to framework. Change calculations to first group and then

average those groupings and the way up the framework.  Likert scores for
a survey_item are averaged.  Then all the survey_items in a scale are
averaged.  Then student scales in a measure are averaged.  And teacher
scales in a measure are averaged.  Then the average of those two
calculations becomes the score for a measure.  Then the measures in a
subcategory are averaged.
