/**
*	Get a list from the parsed xml array
*
* A common way to format lists in xml is
* <tag>

* 	<subtag />
*   ...
* </tag>
*
* The problem is a single item is ambiguous
* <tag>
* 	<subtag />
* </tag>
*
* It could be a one element list or it could be a scalar child -- we only
* know from the context of the data, which the parser doesn't know.  Our parser
* assumes that it is a scalar value unless there are multiple tags with the same
* name.  Therefor so the first is rendered as:
*
* tag['subtag'] = array (0 => $element, 1 => $element)
*
* While the second is:
*
* tag['subtag'] = $element.
*
* Rather than handle each list element as a special case if there is only one item in the
* xml, this function will examine the element passed and if it isn't a 0 indexed array
* as expect will wrap the single element in an array() call.  The first case is not
