Spell check on content added by user

[wrussell1999]

Be able to check that Experience, Education and Skill do not contain any spelling errors. This should be triggered by the user from the client. The format returned should follow this format:

[
    {
        "before": "Hellq there",
        "after": "Hello there"
    }
]

If a better format can be found, this must be discussed with your Pod Leader to make sure the fellows contributing to the JavaScript repository can build functionality to match it.

This should include a test in test_pytest.py to show that it works correctly.
