Comparison with shapeless-scalacheck? about scalacheck-shapeless HOT 2 OPEN

You're right, I was thinking at the beginning to just submit scalacheck-shapeless to shapeless-contrib (typelevel/shapeless-contrib#28), but it finally remained a separate project. I'm checking about the status of shapeless-contrib, and I think I'll add back a mention about it in the README once I'll know more.

For now, the main difference is that scalacheck-shapeless depends on more recent versions of both shapeless (2.1-RC1) and scalacheck (1.12.1).

The coproduct support in scalacheck-shapeless is also more finely tuned, as all cases of the coproduct are given the same weight, which doesn't seem to be the case in shapeless-contrib.

The internals of both projects differ too: scalacheck-shapeless uses Lazy, which was added in shapeless 2.1, whereas shapeless-contrib uses TypeClass, which is less flexible than Lazy.
