Add helpful information to the SETUP.md about rust HOT 9 CLOSED

This is hard to do at the moment since we're not sure yet how the tests will run in the future (i.e. whether cargo will be involved or not).

I just submitted another PR (#26) to get all the examples working with Cargo.
If everybody likes the way that works out, I could write the setup file and some README's which would:

1. Point to the Rust install page (all versions should come with cargo)
2. Telling the user that once they create a file they can cd into a exercise directory and run cargo test to compile and run all the tests.

The question is should we follow the Nightly or Beta channel?

from rust.

Yeah, it's better to hold off until that has been resolved.

@bitborn We would only have to recommend Nightly or Beta until May 15th, which is when 1.0.0 is planned to ship.

I don't really understand where exactly the SETUP.md file is included.

from rust.

When the README for each exercise is assembled, it takes:

• The name of the exercise (based on the directory name for the problem)
• The shared description from $PROBLEM.md from x-common https://github.com/exercism/x-common)
• The contents of SETUP.md
• The source information from $PROBLEM.yml

from rust.

In that order I assume?

Here it is: #28

Yup, looks great.
