Fixed issue #4 - "Only variables should be assigned by reference"

"As of PHP 5, the new operator returns a reference automatically, so assigning the result of new by reference results in an E_DEPRECATED message in PHP 5.3 and later, and an E_STRICT message in earlier versions." - from http://php.net/manual/en/language.operators.assignment.php
