"What if" routing

Mostly dedicated to cruisers - not good for racing - here is a new feature.Think it like "What if I keep sailing at 50 degrees of the true wind, starboard tack, for 3 days?". Or "What if I keep heading 230 true for 5 days?".
This shows you where you would be! There are some limitations of course, like when you keep sailing head to wind, you wacky weirdo.
