     * Converts a simpleXML element into an array. Preserves attributes and everything.

     * you define.
     * For example, for a given element
     * <field name="someName" type="someType"/>
     * if you choose to flatten attributes, you would get:
     * $array['field']['name'] = 'someName';
     * $array['field']['type'] = 'someType';
     * If you choose not to flatten, you get:
     * $array['field']['@attributes']['name'] = 'someName';
     * _____________________________________
     * Repeating fields are stored in indexed arrays. so for a markup such as:
     * <parent>
     * <child>a</child>
     * <child>b</child>
     * <child>c</child>
