-- This gets the Information about an spreadsheet.
-- In order to be able to run these examples you need to
-- create a service acount from google's developers console
-- and copy the dowloaded json file to ~/.config/gcloud/application_default_credentials.json.
--
-- you must also share with your service the spreadsheet that you want to get the info of.
-- In order to do this you must share the sheet with the email address of your service
-- which is in your downloaded service config file.
--
-- after doing above step just pass the sreadsheet id to the function.
