Strikingly similar to fromXor found in XorT, this adds fromOption to OptionT wrapping the Option in the appropriate applicative.

Great catch, thanks for making things consistent.

One tiny request: can you reformat your scaladoc comments? In Cats we have been using:

/**
 *
 */

(I.e. the stars align on the left not the right.)

Once that issue is resolved, 👍 from me too.
