The application needs to do the following:
A) The user gives any necessary authentication needed for google, as well as their email address.
B) Every day the user gets an email letting them know the total number of visits to their site the previous day. The PHP file needs to be able to send the emails, I'll set up a cron job on my end to make it run daily.
C) This should work for any number of users (not just 1).
D) This should be set up using the Google Analytics API.
The only data that needs to be emailed is the total number of visitors the previous day.
