Development

- Removed temporary `RouterException` class.
- Added object-types to parameters in `CallbackExceptionHandler` and `SimpleRouter` classes.
- Router now renders groups even if callback is null.
- Renamed `setMiddleware` to `addMiddleware` in `Route` class and `IRoute` interface.
- `addMiddleware` now accept both object and class strings in `Route` class.
- `addExceptionHandler` now accept both object and class strings in `RouteGroup` class.
- Added unit-test for rewrite-exception message change: `testRewriteExceptionMessage` in `RouterRewriteTest`.
- Fixed typo: renamed `testSimularUrls` to `testSimilarUrls` in `RouterUrlTest`.
