/*
Use a Mixin to Add Common Behavior Between Unrelated Objects:
Create a mixin named glideMixin that defines a method named glide.
Then use the glideMixin to give both bird and boat the ability to glide.

- Your code should declare a glideMixin variable that is a function.
- Your code should use the glideMixin on the bird object to give it the glide method.
- Your code should use the glideMixin on the boat object to give it the glide method.
