(suggestion)fps2ms

What about add fps to ms converting into library?
So if i want to export animation with specific framerate, after creating grid, i can define it as:

animation = grid1("1-8", 1), anim8.fps2ms(24))

instead of cryptic:

animation = grid1("1-8", 1), 0.041666667)

or

animation = grid1("1-8", 1), 1 / 24)

So it can be more readable?
While i can manually define it as:

anim8.fps2ms = function(fps)
return 1 / fps
end

I rather prefer have it available out-of-box
What to you think?
