 /**
  * Multi-purpose function.
  * Use pq() as shortcut.
  *
  * In below examples, $pq is any result of pq(); function.
  *
  * 1. Import markup into existing document (without any attaching):
  * - Import into selected document:
  *   pq('<div/>')				// DOESNT accept text nodes at beginning of input string !
  * - Import into document with ID from $pq->getDocumentID():
  *   pq('<div/>', $pq->getDocumentID())
  * - Import into same document as \DOMNode belongs to:
  *   pq('<div/>', \DOMNode)
  * - Import into document from phpQuery object:
  *   pq('<div/>', $pq)
  *
  * 2. Run query:
  * - Run query on last selected document:
  *   pq('div.myClass')
  * - Run query on document with ID from $pq->getDocumentID():
  *   pq('div.myClass', $pq->getDocumentID())
  * - Run query on same document as \DOMNode belongs to and use node(s)as root for query:
  *   pq('div.myClass', \DOMNode)
  * - Run query on document from phpQuery object
  *   and use object's stack as root node(s) for query:
  *   pq('div.myClass', $pq)
  *
  * @param string|\DOMNode|\DOMNodeList|array	$arg1	HTML markup, CSS Selector, \DOMNode or array of \DOMNodes
  * @param string|PhpQueryObject|\DOMNode	$context	DOM ID from $pq->getDocumentID(), phpQuery object (determines also query root) or \DOMNode (determines also query root)
  *
  * @return PhpQueryObject|QueryTemplatesSource|QueryTemplatesParse|QueryTemplatesSourceQuery|QueryTemplatesPhpQuery|false
  * phpQuery object or false in case of error.
