Logger

public class Logger extends Object

The evaluator may pass an instance of this class to operators and expressions during evaluation. They should use this to log any warning or error messages that might come up. This allows all of our logging policies to be concentrated in one class.

Errors are conditions that are severe enough to abort operation. Warnings are conditions through which the operation may continue, but which should be reported to the developer.
