/**
 * Converts a simpleXML element into an array. Preserves attributes and everything.
 * You can choose to get your elements either flattened, or stored in a custom index that
 * 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>
 * </parent>
 * you array would be:
 * $array['parent']['child'][0] = 'a';
 * $array['parent']['child'][1] = 'b';
 * ...And so on.
 * _____________________________________
 * @param simpleXMLElement $xml the XML to convert
 * @param boolean $flattenValues Choose wether to flatten values or to set them under a particular index. defaults to true;
 * @param boolean $flattenAttributes Choose wether to flatten attributes or to set them under a particular index.  Defaults to true;
 * @param boolean $flattenChildren Choose wether to flatten children or to set them under a particular index. Defaults to true;
