NSErrorException class final

Wrapper Exception around an Objective-C NSError.

In Dart, an "exception" is an ordinary runtime failure that can be caught and handled, while an "error" is a program failure that the programmer should have avoided (and catching Errors is bad practice).

Objective-C inverts this nomenclature. Ordinary runtime failures are signaled using NSError, so these are analogous to Dart's Exceptions, though they're returned by reference rather than thrown. On the other hand, NSException is intended to be used in an @throw statement, and not intended to be caught (in fact Objective-C doesn't intend throwing and catching to be part of an ordinary control flow at all).
