Analytics reports

Hi Cait,
Take a look at these changes when you have a chance 

-- You will need to:
  *  run a migration to add semesters to courses.
  *  Add a start and end date to your courses in the options panel
  *  Check out the students and staff panels under the systems analytics.

I'm not seeing any metrics under my local staff interactions, but I think it's has to do with not having any of this data in my local environment -- let me know if it looks suspicious to you based on your data. I'm updating the create analytics rake task to work within a semester schedule now.
