  The purpose of this script is to create google login credentials to be used by google drive
  writer.
  
  Expected workflow is:
  
  1.- Get the client secret file. If you haven't one, please follow this tutorial:
  https://developers.google.com/drive/web/quickstart/python
  
  2.- Execute this script. It will open a browser tab in which you have to login with your
  Google account. It will create a credentials file (file path will be printed).
  
  3.- You can use the info contained in both files to configure a export using google
  drive writer.
