A cache busting extension for StealJS
npm install steal-cache-bust

A StealJS and SystemJS cache busting extension.
You can install through NPM:
```
npm install steal-cache-bust --save
You'll then want to copy node_modules/steal-cache-bust/cache-bust.js to a location within your project folder. In the future this extension will be included in Steal by default.
With StealJS simply include cache-bust as a configDependency. Assuming you placed it in your root folder:
`json
{
"system": {
"configDependencies": [
"cache-bust"
]
}
}
`
You can configure cache busting by setting properties on the script tag. You'll probably at least want to set cacheVersion.
This is the version string that will be appending as a query parameter. For example if you do:
`html`
Then requests will be for:
``
http://example.com/foo/bar.js?version=14
By default "version" is used as the query param for busting caches but you can use a different string by setting cacheKey`.
