Report using a member of the Debug module

• Debug.todo marks missing functionality which needs to be added gradually
• Debug.log is a quick and dirty way to display an elm value in the console and can for example be used to inspect private (opaque) types. It's nothing a published product should make use of.
• Debug.toString is a quick and dirty way to display an elm value anywhere, similar to Debug.log

Using any Debug member also prevents compiling in optimized mode and publishing as a package.
