add tests to validate existing exception hierarchy, in preparation for adjustment. add \RuntimeException wrapper. update all extensions of \RuntimeException to extend the wrapper. spl-exception wrappers now implement a common exception interface for this package. this allows consumers to handle all custom exception types thrown by catching the common interface rather than by catching each specific extension or their spl parents.
