* level of name 'name' with values of 'blue' and 'red' respectively.
* - Flow::add('name', array('sub1'=> 'blue','sub2'=>'red')); results in a
* new node of name 'name' at rool level, which contains 2 children
* each with the values of blue and red respectively.
*
* Note that multi level arrays can be used.
