+	* This method takes an array and converts it into an xml.
+	* There are several noteworthy cases:
+	*
+	*  If array contains a key '_element', then the code assumes that ALL other keys are not important and replaces them with the value['_element'].
+	*	Example:	name='root',  value = array( '_element'=>'page', 'x', 'y', 'z') creates <root>  <page>x</page>  <page>y</page>  <page>z</page> </root>
+	*
+	*  If any of the array's element key is '*', then the code treats all other key->value pairs as attributes, and the value['*'] as the element's content.
+	*	Example:	name='root',  value = array( '*'=>'text', 'lang'=>'en', 'id'=>10)   creates  <root lang='en' id='10'>text</root>
+	*
+	* If neither key is found, all keys become element names, and values become element content.
+	* The method is recursive, so the same rules apply to any sub-arrays.
