[Feature Request] Diagramming

[jebbster88]

I often like to map out processes/workflows with my notes, and would prefer not to have to edit them externally and import images/pdfs into cryptee.

Would be possible to integrate something like mermaid.js into the editor to allow for dynamic rendering of diagrams? PlantUML would be even better, but that would require server-side infrastructure for rendering, which wouldnt work with Cryptee's security model. Mermaid, I believe, could be done entirely client-side.
