Issue Summary

i'm really happy to see this module came up. i was about to tweak the a/b test for multi testing.

some ideas:

if would be great to have a textfield with values for every variant. this should be able to get called from within the template. this way there are limitless possibilities for testing, even content copy could be tested.
i'm not sure that already works.
the same function sould be able to return the index numer of the variante. so in case you had 6 variants you could switch 6 different layouts with a php case stch construct.

anyway, good work, tell me if there is something i could contribute.
