rest.class.php

<?php
/*
	Usage:
	
		$rest = new REST($config);
		
		$result = $rest->get('http://example.com/method, array(
			'name' => 'value',
			...
		));
		
		echo $result->response;   // raw response data
		echo $result->http_code;  // resulting HTTP code
		
	Config options:
	
		$config = array(
			
			// Basic auth:
			'auth_user' => 'username',
			'auth_pass' => 'password',
			
			// Set headers:
			'headers' => array('Name: value', ...)
			
		);
	
	Or later on:
		
		$rest->set_headers('Name: value');
		
		$rest->set_auth('user', 'pass');
