data-tree-print-0.1.0.2: Print Data instances as a nested tree

Provides functionality similar to that of the Show class: Taking some arbitrary value and returning a String.

• Output is not intended to be valid haskell.
• Requires a Data instance instead of a Show one.
• Output, if large, is often easier to parse than show output due to the formatting as a nested tree.
• The user can adapt the behaviour at runtime using custom layouting expressed via syb-style extension.
