feature request

• What is the current behavior?

<code></code> blocks render with basic white-text-on-black styling without syntax highlighting features.

• If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem via
  https://plnkr.co or similar (you can use this template as a starting point: http://plnkr.co/edit/tpl:AvJOMERrnz94ekVua0u5).

Not a bug

• What is the expected behavior?

Language-specific syntax highlighting should be rendered for <code></code> blocks where a language is appropriately specified in the markdown.

• What is the motivation / use case for changing the behavior?

Improve visual display of code elements

• Please tell us about your environment:

• Version: 0.1.0 at Dev #71
• Browser: all
• Language: all

• Other information (e.g. detailed explanation, stacktraces, related issues, suggestions how to fix, links for us to have context, eg. stackoverflow, gitter, etc)

Implementation would likely involve the use of highlight.js or Prims.js, either directly or through their associated unified plugins, rehype-highlight and rehype-prism, respectively. See this page for more information.
NOTE: Special attention may need to be paid to the interaction between this feature and the rehype-sanitize plugin.
