🛠 Moved Pretty-CLI into Ghost-Utils repo

- this was originally created in the slimer repo, as that's where it was first used
- it's also used in migrate, should be used in gscan, and hopefully eventually, will also be part of Ghost-CLI
- therefore, it belongs somewhere more general

+# Pretty CLI
+
+A mini-module to style a [sywac](http://sywac.io/) instance in a standard way
+
+## Install
+
+Either: `npm install @tryghost/pretty-cli --save`
+
+Or: `yarn add @tryghost/pretty-cli`
+
+## Usage
+
+E.g. `const prettyCLI = require('@tryghost/pretty-cli');`
+
+`prettyCLI` is a pre-styled instance of the [sywac](http://sywac.io/) API.
+
+See the [sywac quickstart](http://sywac.io/docs/) and [config guide](http://sywac.io/docs/sync-config.html) for full usage.
+
+Example:
+
+```
+#!/usr/bin/env node
+const prettyCLI = require('@tryghost/pretty-cli');
+
+
+prettyCLI
+  .command({
+    flags: 'myTask [option]',
+    desc: 'Run myTask',
+    run: (argv) =>  { ... do something here }
+  })
+  .parseAndExit();
+```
+
+You can also grab a fresh instance of the api with `prettyCLI.Api.get()`.
+
+The style rules used are available at `prettyCLI.styles`.
+
+## Test
+
+- `yarn lint` run just eslint
+- `yarn test` run lint && tests
