mermaid: Generate flowcharts and diagrams from text using Node.js

Now ya’ll know I love me some Markdown, and while this isn’t quite a pretty to read in text format as Markdown is, mermaid scratches a similar itch for me. It provides a way to represent flowcharts and diagrams using text, making it easy to easily store and compare them in your source control repository.
