Say you have nested case classes that you'd like to examine. One convenient method is to just dump them in a tree form.

Basic usage:

import scala.util.dump._

// Example case class
case class Scenario(agents: List[Agent], modes: Array[String], name: String, id: Long)
case class Agent(num: Int, times: Map[String, Double])

// Some data
val a1 = Agent(1, Map("baseline" -> 2.0, "tolls" -> 5.0))
val a2 = Agent(2, Map("baseline" -> 3.0, "tolls" -> 2.3))
val s = Scenario(List(a1, a2), Array("baseline", "tolls"), "trial", 42)

// Dump!
println(AsciiTreeView(s))

The output is:

Scenario
  agents = [
    Agent
      num = 1,
      times = {
        baseline -> 2.0,
        tolls -> 5.0
      },
    Agent
      num = 2,
      times = {
        baseline -> 3.0,
        tolls -> 2.3
      }
  ],
  modes = [
    baseline,
    tolls
  ],
  name = trial,
  id = Long

It wouldn't be hard to make a graphical viewer too using Swing's JTree.
