/**
* Array to XML
*
* Converts an array into XML tags (recursive).
* Converts an array into XML tags (recursive). This method expects the
* passed array to be formatted very specifically to accomodate the fact
* that an array's format isn't quite the same as well-formed XML.
*
* Input Array =
* array('children' => array(
* 'child' => array(
* array('name' => 'Wendy Darling'),
* array('name' => 'John Darling'),
* array('name' => 'Michael Darling')
* )
* ))
*
* Output XML =
* <children>
* <child><name>Wendy Darling</name></child>
* <child><name>John Darling</name></child>
* <child><name>Michael Darling</name></child>
* </children>
*
* @access private
* @param array $array array to convert into XML
* @return string generated XML
* @todo Method sucks, should replace
