/**
* Get the number of child nodes
*
* If the direct parameter is set to true, only the direct children are counted (based upon the parent_id field)
* If false is passed for the id parameter, all top level nodes are counted, or all nodes are counted.
*
* Scoped behavior:
*
* If the model is scoped and the id parameter is given it will automatically set the scope. To count the top
* level nodes you have to pass the scopeField as the id parameter.
*
* Example: array('scope' => 5) or array('id' => false, 'scope' => 5)
*
* @param AppModel $Model Model instance
* @param mixed $id The ID of the record to read or false to read all top level nodes
* @param boolean $direct whether to count direct, or all, children
* @return integer number of child nodes
* @access public
* @link http://book.cakephp.org/view/1347/Counting-children
