* Parse a query string given in SMW's query language to create

* An object of type SMWQuery is returned.
*
* The format string is used to specify the output format if already
* known. Otherwise it will be determined from the parameters when
* needed. This parameter is just for optimisation in a common case.

* @param array $params These need to be the result of a list fed to getProcessedParams
