Can now use un$Method() for all unSet of $Method

<?php include('surikat/control.php');control::dev();
use model\SQLComposer;
use model\Query;
function test($s){
	$s->from('(SELECT test FROM virtual WHERE foo IN
(?,?,?,?))',array('bar1',1,2,3));

	$s->where('foo3=:a AND foo4=:a',array('bar3','bar4'));
	$s->where('foo5=:foo5',array('foo5'=>array('bar5','bar5.2')));
	$s->unWhere();
	echo '<pre>';
	echo $s->getQuery()."\r\n";
	print_r($s->getParams());

}
test( SQLComposer::select() );
test( new Query('table') );
