Mermaid diagram support added

Just showcasing some of the diagrams I’ve added tooling for. We may still have some style issues to work out. I grabbed these samples from a great site, Mermaid Live Editor.

Sample ER diagram

Class Diagram

May be missing a much-needed CSS style here.

classDiagram
    Animal <|-- Duck
    Animal <|-- Fish
    Animal <|-- Zebra
    Animal : +int age
    Animal : +String gender
    Animal: +isMammal()
    Animal: +mate()
    class Duck{
      +String beakColor
      +swim()
      +quack()
    }
    class Fish{
      -int sizeInFeet
      -canEat()
    }
    class Zebra{
      +bool is_wild
      +run()
    }
