* Recursively flatten an array. So that array('key1' => array('key2' => 'value')) becomes array(key1.key2 => value)
* You can also parse it into html using the options array. The default parsed output is an unordered list.
*
* @var array Any multi-dimensional array
* @var array Options, separator, parse, start, startItem, betweenItem, endItem, end.
* @return array When parse is false (default) you get a flattened array returned. Where you can specifiy the separator. $options['separator']. The output is array(key1[$options['separator']key2 => value);
* @return string When parse is true, by default you get an unordered list returned, but you can also control each piece of html surrounding the values. Default is <ul><li>key1.key2 : value</li></ul>
