Description

As an integrator/user of this library:

I want to render flows serverside

So that: we can protect IP, cache flow diagrams, other

Acceptance Criteria

• can render single flow given an flow TAB ID
• can render multiple flow tabs
• can generate CSV scoped to given name

This is almost possible. By design, the code was written with this support in mind however there is some missing technology - namely there is not bounding box (or measurements functions) in node-dom so rendering fails.
