Add reporting/charts based on feedback and logging sheets

[barrybecker4]

Some ideas for the sort of reports to offer:

By combining the data in the match request log, the “Tutor Session Complete”, and Tutee Session Complete” form responses, we should be able to do some rich data analysis. It should be easy to produce the following reports:

• Show all AVAILABLE tutors that have no active tutees.
• Show all AVAILABLE tutors that are actively meeting with tutees more than N times a week (sorted by activity).
• Show all UNAVAILABLE tutors that have not been meeting with tutees at least N times a week (sorted by inactivity).
• Show tutors sorted by amount of tutoring hours in the last N weeks.
• Show tutoring hours over time for all active tutors.
• Show total tutoring hours for each tutor that had them (sorted by hours).
• Show summary results for all tutee feedback provided to any given tutor.
• Show aggregated tutee feedback to help understand the effectiveness of the program and of individual tutors.
