Feature: Config Creation Wizard

I've been working on a project to create a config wizard for .babelrc. I'm hoping to go through some iterations based on feedback, and eventually get it included in the site as either a link or an embed.

[Demo] | [Source]

Example output:

```json
{
"plugins": [
"transform-class-properties",
"transform-object-rest-spread"
],
"presets": [
[
"env",
{
"targets": {
"browsers": [
"> 1%"
]
}
}
],
"react"
]
}
```

Any feedback is appreciated, either here or in [config-wizard issues](https://github.com/brigand/config-wizard/issues/new).

Start with the linked Demo and Source for the config wizard, then review the Babel website structure to determine where a link or embed would belong. The issue is done only when the wizard's inclusion in the site has a decided approach and the resulting integration is available to users.
