make code-only version of notebooks available

[fredzannarbor]

Description of the feature request:

The example notebooks are great, but if, like me, you are not big into notebooks, you may want to be able to just extract the code without all the explanatory Javascript. Another folder with "code-only examples" would do the trick.

What problem are you trying to solve with this feature?

ease of access to code samples

Any other information you'd like to share?

Mentioned this to @logankilpatrick who liked idea.
