* This example differs from others in that it will reattempt a request if
* the timestamp is detected to be off from the Twitter servers.
*
* Instructions:
* 1) If you don't have one already, create a Twitter application on
* https://dev.twitter.com/apps
* 2) From the application details page copy the consumer key and consumer
* secret into the place in this code marked with (YOUR_CONSUMER_KEY
* and YOUR_CONSUMER_SECRET)
* 3) From the application details page copy the access token and access token
* secret into the place in this code marked with (A_USER_TOKEN
* and A_USER_SECRET)
* 4) Visit this page using your web browser.
