BaseError
util~ BaseError
Extensible error class.
The built-in Error class is not actually a constructor, but a factory. It
doesn't operate on this, so if we call it as super() it doesn't do
anything useful.
Nonetheless it does create objects that are instanceof Error. In order to easily subclass error we need our own base class which mimics that behavior but with a true constructor.
Note that this code is specific to V8 (due to Error.captureStackTrace).
