Katrina Owen 6151955420 Generate static exercise README templates

We are working towards making exercises stand-alone. That is to say: no more generating READMEs on the fly.

This will give maintainers more control over each individual exercise README, and it will also make some of the backend logic for delivering exercises simpler.

The README template uses the Go text/template package, and the default templates generate the same READMEs as we have been generating on the fly.  See the documentation in [regenerating exercise readmes][regenerate-docs] for details.

The READMEs can be generated at any time using a new 'generate' command in configlet. This command has not yet landed in master or been released, but can be built from source in the generate-readmes branch on [configlet][].

Raindrops

Convert a number to a string, the contents of which depend on the number's factors.

If the number has 3 as a factor, output 'Pling'.
If the number has 5 as a factor, output 'Plang'.
If the number has 7 as a factor, output 'Plong'.
If the number does not have 3, 5, or 7 as a factor, just pass the number's digits straight through.

Examples

28's factors are 1, 2, 4, 7, 14, 28.
- In raindrop-speak, this would be a simple "Plong".
30's factors are 1, 2, 3, 5, 6, 10, 15, 30.
- In raindrop-speak, this would be a "PlingPlang".
34 has four factors: 1, 2, 17, and 34.
- In raindrop-speak, this would be "34".

Elm Installation

Refer to the Exercism help page for Elm installation and learning resources.

Writing the Code

The first time you start an exercise, you'll need to ensure you have the appropriate dependencies installed.

$ npm install

Execute the tests with:

$ npm test

Automatically run tests again when you save changes:

$ npm run watch

As you work your way through the test suite, be sure to remove the skip <| calls from each test until you get them all passing!

Submitting Incomplete Solutions

It's possible to submit an incomplete solution so you can see how others have completed the exercise.
