Requirements: 
 - sudo pip install --upgrade google-api-python-client

Create a Service Account
1) Go to https://console.developers.google.com/permissions/serviceaccounts
2) Select a Project for the Service Account to created in (if you don't have a Project yet, click 'Create' and follow this process)
3) Click 'Create Service Account'
4) Type a name and also click 'Furnish a new private key'
5) Then choose 'P12' as the file Type
6) Click create and save the P12 file to your computer next to the Python script

Setup Analytics property
1) Navigate to your View in Analytics (under Admin)
2) Under the View, go to 'Users'
3) Add the Service Account you just created as a user (you can find the service account email address in the developer console. It will look something like test-7@dashboard-170303.iam.gserviceaccount.com)
4) Under the View, go to 'View Settings' and find the value of 'View ID'

In the Python script, replace these variables with the correct values:
 - service_account_email
 - key_file_location
 - VIEW_ID
