/**
*
* 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.
