/**
* 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 bool $flattenValues Choose wether to flatten values
* or to set them under a particular index.

* @param bool $flattenAttributes Choose wether to flatten attributes

* Defaults to true;
* @param bool $flattenChildren Choose wether to flatten children
* or to set them under a particular index.
* Defaults to true;

* false. Defaults to "@attributes"
* @param string $childrenKey index for children, in case $flattenChildren was set to
