/**
* Slinky allows you to go back and forth between "long" and shortened URLs
* using popular URL shortening services.
*
* Slinky assumes you have cURL installed and working, and requires the JSON
* extension installed if you're working with a service that uses JSON.
*
* Slinky will ONLY work with PHP5+
*
* It supports some of the more popular services, with easy extensibility for
* adding your own relatively easily. It defaults to using TinyURL
* for shortening URLs. If you want to use some of the other services, you need
* to set some configuration options before actually shortening/lengthening
* URLs. I'd strongly suggest that you cache results using memcached, a local
* DB or whatever to avoid having to hit APIs etc every time you encounter a
* URL.
*
* Slinky supports shortening, and auto-detection (for lengthening URLs)
* using these services:
* - Bit.ly
* - Tr.im
* - TinyURL
* - Is.Gd
* - Fon.gs
* - Micurl.com
* - ur1.ca
* - Ptiturl
* - Tighturl
* - 2tu.us
* - Snipr / Snipurl / Snurl.com / Sn.im
*
*
* To use Slinky:
*
* $slinky = new Slinky( 'http://dentedreality.com.au/' );
* - Creates a new Slinky instance, will default to using TinyURL for ->short();
*
* $slinky = new Slinky( 'http://dentedreality.com.au', new Slinky_Bitly() );
* - Creates new Slinky, forces use of Bit.ly for ->short();
*
* $slinky = new Slinky( 'http://dentedreality.com.au/' );
* echo $slinky->short();
* - echos the short version of http://dentedreality.com.au/ (default to TinyURL)
*
* $slinky = new Slinky( 'http://tinyurl.com/jw5sh' );
* echo $slinky->long();
* - echos out the long version of http://tinyurl.com/jw5sh (which should be http://dentedreality.com.au/)
*
* $slinky = new Slinky( 'http://dentedreality.com.au/' );
* echo $slinky->long();
* - Attempts to lengthen the URL, but will not auto-detect which service it is
* so it will just output the original URL. Useful for always attempting to
* lengthen any URL you come across (fails gracefully)
*
* $slinky = new Slinky( 'http://dentedreality.com.au/' );
* $slinky->set_cascade( array( new Slinky_Trim(), new Slinky_IsGd(), new Slinky_TinyURL() ) );
* echo $slinky->short();
* - Uses the powerful cascade mode to make sure that we get a short URL from
* Tr.im, Is.Gd or TinyURL (in that order).
*
* See specific service class definitions below for examples of how to use them,
* as some services allow (or require) additional properties before you can use
* them (for authentication etc).
*
* To use a different service with Slinky, just create your own class and
* extend Slinky_Service(). Make sure you implement url_is_short(), url_is_long(),
* make_short() and make_long(). If you need to GET or POST a URL, you can use
* ->url_get() and ->url_post(), which your class will have inherited.
