Templating support instead of polluting CSS with HTML

[robhrt7]

Hi,

Does hologram supports, or plan to support templates include from CSS comments? Like

/*
My example

\```html_example
    @inclute template.hbs
\```
*/

HTML placed in CSS comments is hard to maintain, and easpecially keep up to date, because of you're always forced to copy paste it from real codebase to comments. Also, you don't have any syntax highlight and writing bigger chunks of HTML examples will bloat your CSS.
