 /**
  * Recreates object by calling the constructor with parameters
  * that match the array keys (recursively for objects)
  *
  * Example:
  * <pre>
  * public static function fromArray($obj) {
  *     return SerializeHelper::createClassFromArray(get_called_class(), $obj);
  * }
  * </pre>
  *
  * Requirements:
  *
  * 1) Constructor parameters that are objects need to be type hinted
  *
  * 2) Constructor parameters that are objects need to implement {@see SerializableInterface}
  *
  * 3) Constructor parameter names need to match the class variable names
  *
  * @param string $className
  * @param array $obj
  * @throws NotSerializableException If a constructor takes an object that
  *                                  does not implement {@see SerializableInterface}
  *                                  or if the class does not exist
  * @return $this
