/**
* This file defines the 'LinkedIn' class. This class is designed to be a
* simple, stand-alone implementation of the LinkedIn API functions.

*
* SOURCE CODE LOCATION:
*
* http://code.google.com/p/simple-linkedinphp/
*
* REQUIREMENTS:
*
* 1. You must have cURL installed on the server and available to PHP.
* 2. You must be running PHP 5+.
*
* QUICK START:
*
* There are two files needed to enable LinkedIn API functionality from PHP; the
* stand-alone OAuth library, and this LinkedIn class. The latest version of
* the stand-alone OAuth library can be found on Google Code:
*
* http://code.google.com/p/oauth/
*
* Install these two files on your server in a location that is accessible to
* the scripts you wish to use them in. Make sure to change the file
* permissions such that your web server can read the files.
*
* Next, make sure the path to the OAuth library is correct (you can change this
* as needed, depending on your file organization scheme, etc).
*
* Finally, test the class by attempting to connect to LinkedIn using the
* associated demo.php page, also located at the Google Code location
* referenced above.
