Add explanation of using arrays for filter2 into usage document #195

I recently spent some time screwing up array searches and after researching how govaluate handles them managed to figure it out. I've updated the documentation with examples to reflect that.

Cheers

Yesterday, I found the in keyword as well. Having it documented would be great.

BTW: There is no not in. Instead one can use !($number in (1, 2, 3, 5, 8, 13)).
