spring shell sample (REPL)

We are using Spring shell, and it worked really well for us. Some of its features:

• A simple, annotation driven, programming model to contribute custom commands
• Use of Spring’s classpath scanning functionality asthe basis for a
  command plugin strategy and command develoment
• Inheritance of the Roo Shell features, most notably tab completion, colorization, and script execution.
• Customization of command prompt, banner, shell history file name.
