Making decrypt accessible

[emitanaka]

At the moment the decryption of lineup() is printed as a message and it's hard to capture it programmatically. I wonder perhaps saving this to .Last.value or some special function to extract it will be useful? (Or maybe there is one already?)

Yes, it's been an issue. We had looked at this before but there wasn't a good way to do this.

The best approach is to generate the position outside of the lineup function, and pass it in with the pos argument.

You can just add it as an attribute to the object.

Ok, want to do the pull request
