Pretty print with indentation

[channingwalton]

Thanks for this plugin - very useful.

Having an option to pretty print would be nice:

User(
  name = Joe,
  age = 18,
  address = Address(
    line1 = "…"
    …
  )
)

For large, deeply-nested case classes it would help readability.

On one hand I'd be inclined to at this, on the other hand we've historically avoided configuration to keep the implementation relatively simple...

maybe the option to replace toString implementations with a call to pprint would be enough?
