UnexpectedErrors Class
Utility for handling/reporting unexpected runtime errors. This class establishes a global handler for
unexpected errors, and programmers should use its handle method when they occur. Generally, unexpected
errors should not cause program termination, and should instead be logged and swallowed. However, for
development/debugging, it can be helpful to re-throw exceptions so they are not missed.
