Fatal Error Class 'SiteSearch' not found

Hi there,

I get a the above message for examples.php or when i try to create a new SiteSearch object in my project.
Tried the following setup:
1. Have SiteSearch.php and SiteSearchException.php in the same folder as my project files.
2. include SiteSearch.php and SiteSearchException.php in my project file as follows:

<?php

use Search\Google,
Search\Google\Exceptions;

require_once 'SiteSearchException.php';
require_once 'SiteSearch.php';

$search = new SiteSearch('CSE Key Here', 'utf-8', GoogleCustomSearch::HTML);

Am I missing something?
Thank you for the help.
