Hi all,
is there a way to retrieve variation id for a test?

$test = new Test('homepage_color', array(
'white' => 1,
'black' => 1,
'yellow' => 1,
));

$test->getVariation(); // black

$test->getVariationId(); // 2

It should be useful in case of multivariation test to obtain a cross test unique id (tracking + analytics purpose).

Thanks,
Fabio
