Markdown Babel: execute source code blocks in your editor like Emacs org-mode

Execute code snippets, generate graphs from code, plot ... err... your plots. -- With a client/editor extension to do the character offset calculation for you, you can put the cursor into a code block, invoke md-babel on it, and get the computation result inlined into the document. Not side-effect free: if you configure plantuml or Mermaid for this, it will generate image files for you. Repeat calls will update the result.
