Get a stream feed from a Twitter user
*** CAREFULLY READ THE NOTES **** *** THIS DOES NOT WORK "OUT OF THE BOX" *** You'll need a few minutes of CAREFUL reading before making your own Twitter feed: In 2010 simple command line Twitter feed requests all stopped working because Twitter upgraded to SSL security. Https requests for a filtered Twitter stream feed now require a special header called "oauth_header". The benefit is that your stream feed and login info is securely encrypted. The bad news is that an "oauth_header" takes some work to build. Fortunately, four functions, imaginatively named step1, step2, step3 and step4 can be used to build a customized oauth_header for you in a few minutes. Now, go look at "step1" to start creating your own oauth_header!
