Chapter 11 Test #4 and #5

I'm getting odd values for my color calculations in tests 4 and 5 in the reflection section-

The tests are line in world.rs starting on lines 349 and 367

I've put in some debug statements in shade_hit to see what's going on-

It looks to me like the green of the default world sphere is instantly only getting ambient because it's coming up as in shadow, but if the ray is cast down and bouncing up to the bottom of the sphere then I think that's correct anyway?

Neither of my calculated colors (left side) are even close though.
