# We'll want to automatically send the user to the authorization URL
# and probably also pass in a callback URL so that the user is seamlessly redirected back to your app after pressing a button
#

# Once the user has successfully granted permission to your app
# we can upgrade the now-authorized request token to an access token

# This will fail if the user didn't visit the above URL and hit 'Allow'

# The access token is all you'll need for all future API requests on behalf of this user, 
# so you should store it away for safe-keeping (even though we don't for this tutorial). 
# By storing the access token, you won't need to go through these steps again unless 
# the user reinstalls your app or revokes access via the Dropbox website.

# Now that the hard part is done, all you'll need to sign your other API calls is 
# to pass the session object to DropboxClient and attach the object to your requests.
