     * 
     *  The options passed in must be a Traversable object with option names for keys.
     *  Option names are case insensitive and will be stripped of underscores. By convention,
     *  option names are in lowercase and with underscores separated words.
     * 
     *  The target object is expected to have a setter method for each option passed. By convention,
     *  setters are named using camelcase with a 'set' prefix.
     * 
     *  Example: option_name -> setOptionName()
     * 
     *  @param object $target The object that needs to be configured.
     *  @param \Traversable $options The configuration to apply. Traversable is amongst
                                     others implemented by Zend\Config and arrays
     *  @param boolean $tryCall When true and $target has a __call() function, try call if no setter is available.
     *  @return void Nothing
