Detailed Description

Wrap any exception as BaseException. We don't wrap as Error because we do not usually want to catch these exceptions and we don't use std::nested_exception because we need the dynamic type to preserve the original exception for that. This should never be used to wrap something that already is a BaseError (or a BaseException), but this isn't checked since this should not be thrown often.
