Create CNAME

For now this will live as a GitHub page to serve the assets, but we set
it up to use a CNAME so we can switch the implementation at any time.
To do this you will need to change the CNAME record in DNS.

+
+This repository contains all static assets used for company branding in various applications.
+These include, but are not limited to, images and CSS.
+
+## Use in Your Web Application
+
+For now, these assets are served with GitHub pages.
+To use them, use the following prefix, then the path as illustrated below:
+
+```
+https://assets.nscale.com/<path>
+```
+
+## Conventions
+
+Files, where appropriate, are intuitively named:
+
+* `light` - for use on light backgrounds.
+* `dark` - for use on dark backgrounds.
+* `adaptive` - for use on any background, the image will use the `currentColor` for black/white elements. However this requires the SVG contents to be in the DOM, so you must inject the SVG and not use an `<img>` tag.  You can use [svg-inject](https://github.com/iconfu/svg-inject) to perform this task.
