Use output buffering in "curl"-lib of your code

[eerrap]

Use output buffering in "protected function doCurlCall" in file curl.php to prevent instant output which is not necessary because of return values available!
If this is changed, a developer can decide whether to output the row response from echonest or to process it any further.

May be better not change "curl.php" but change "HttpClient.php" to have the following lines in "request" method:

        ob_start();
        $this->doRequest($url, $parameters, $httpMethod, $options);
        $response = ob_get_contents();
        ob_end_clean();

I've added the raw option on all API objects (see the bottom of the README for more info). Will this accomplish what you're looking for here?
