/** The main REPL related classes and values are as follows.
 *  In addition to standard compiler classes Global and Settings, there are:
 *
 *  History: an interface for session history.
 *  Completion: an interface for tab completion.
 *  ILoop (formerly InterpreterLoop): The umbrella class for a session.
 *  IMain (formerly Interpreter): Handles the evolving state of the session
 *    and handles submitting code to the compiler and handling the output.
 *  InteractiveReader: how ILoop obtains input.
 *  History: an interface for session history.
 *  Completion: an interface for tab completion.
 *  Power: a repository for more advanced/experimental features.
 *
 *  ILoop contains { in: InteractiveReader, intp: IMain, settings: Settings, power: Power }
 *  InteractiveReader contains { history: History, completion: Completion }
 *  IMain contains { global: Global }
