Copy buttons for code blocks about framework

[trebor]

i'm having a look at this. it looks like we are using markdown-it for markdown. so i am exploring these plugins:

• markdown-it-code-copy
• markdown-it-copy

if they aren't fit for purpose, perhaps i can use them as a template for our own plugin.

it's looking like markdown-it-copy might be the correct thing. @byrideout i realized i was trying to work out how this should look and maybe you have a thought on this. currently the cli renders 2 letter type ids into the upper right corner of the box, "js" for javascript:

"md" for markdown.

etc.

do you thoughts on a clean way to incorporate a copy button into this? i also have "success" and "fail" messages which can be rendered based on the copy operation.
