Stage 10.14: Your Own Prelude

Because of standard library's prelude, it's common for your libary to have its own prelude module as a starting point for where users should import all of the most common data structures for using your library (e.g use my_library::prelude::*). It doesn't automatically get used in programs/libraries that use your crate, but it's a good convention to follow so people know where to start.

Ferris says, "Be a good rustacean and help a fellow crab out with a good prelude!"
