babel macro

https://github.com/kentcdodds/babel-macros

```js
import vmark from 'vmark/macro'

const post = vmark`
# hello

`

// ===>

const post = {
render() { /* ... */ }
}
```

Read the linked babel-macros project first, then compare its expected integration with the JavaScript tagged-template example in this issue. Done means the shown vmark/macro import and template produce the illustrated component behavior; the issue names no repository files or tests to run.
