Build a simple library for the pico engine

[windley]

Write a module that interfaces with JSONPlaceHolder.

Your module should:

1. Contains a function that lists all the posts
2. Contains a function that takes an integer and returns the post with that number.
3. Contains an action that creates a new post

Do this first in KRL. And write a ruleset that uses the KRL module.

Next make it a built in module in your copy of the pico engine. Write another ruleset that uses the built-in module.
