• All new features must include a unit test.
  If you've fixed a bug or added code that should be tested, add a test to the
  test directory!

• All new functions and code must be clearly commented and documented.
  If you do make documentation changes, make sure that the docs build and
  render correctly by running make docs.

• Ensure that the test suite passes, by running make test.

• Add a new entry to the doc/releases/changelog-dev.md file, summarizing the
  change, and including a link back to the PR.

• The PennyLane source code conforms to
  PEP8 standards.
  We check all of our code against Pylint.
  To lint modified files, simply pip install pylint, and then
  run pylint pennylane/path/to/file.py.

Thanks @AmintorDusko, looks good already. Left minor comments and questions.

[Jaybsoni]

Just a few comments left to be addressed, then it's ready to go! Great work 💯

[DSGuala]

Looks good to me. Will play around a little bit more with the functionality and leave a final review.

[DSGuala]

Looks good to go from my end. My main feedback is that it will be good to have some more examples in the main resource.__init__ page. It took me some time to set up a custom ErrorOperation with SpectralNormError. But we can address this as we add more features, no need to include it in this PR.

We can update this one in a follow up PR to remove the angle brackets.
