This class provides functionality for rendering diagrams and animations

It can be used in two ways:

• conventionally, via the render methods;
• with special syntax sugar, allowing render calls on the diagrams/animations themselves.

Usage examples:

import reftree.diagram.Diagram
import java.nio.file.Paths

val renderer = Renderer(
  renderingOptions = RenderingOptions(density = 75),
  directory = Paths.get("images", "usage")
)

// With custom output format
val renderer = Renderer(
  renderingOptions = RenderingOptions(density = 75),
  directory = Paths.get("images", "usage"),
  format = "ps" // Or any other format that compatible with dot -T
)

// Conventional usage
renderer
  .tweakRendering(_.withVerticalSpacing(2))
  .render("list", Diagram(List(1)))

// Sweet sugar, recommended
import renderer._
Diagram(List(1))
  .render("list", _.withVerticalSpacing(2))
