Thank you very much for your pull request!

If your PR is the addition of a new operator, please make sure all these boxes are ticked with an x:

- [ ] Add the operator to Rx
- [ ] It must have a `-spec.ts` tests file covering the canonical corner cases, with marble diagram tests
- [ ] If possible, write a `asDiagram` test case too, for PNG diagram generation purposes
- [ ] The spec file should have a type definition test at the end of the spec to verify type definition for various use cases
- [ ] The operator must be documented in JSDoc style in the implementation file, including also the PNG marble diagram image
- [ ] The operator should be listed in `docs_app/content/guide/operators.md` in a category of operators
- [ ] The operator should also be documented. See [Documentation Guidelines](../CONTRIBUTING.md).
- [ ] You may need to update `MIGRATION.md` if the operator differs from the corresponding one in RxJS v4
