Correct Example Style to meet HQRM and Enable Example Tests - Fixes #82

[PlagueHO]

This PR:

• Corrects the examples so that the meet the standards required to enable the Common Tests - Validate Example Files.
• Opts-in to the Common Tests - Validate Example Files tests.
• Renames the example files to support the change over to auto documentation resource module style.
• Ensures all examples in README.MD match examples in files and none are missing.

Note: I could instead link the examples in README.MD instead of keeping copies in there, but as these will very soon be removed anyway due to the move to auto-documentation I didn't bother, as they get automatically assembled anyway.

I did not style check the examples in README.md. Since you will remove them. Why not remove them now and add an Examples header instead pointing to the Examples folder?

Thanks for reviewing @johlju! I've moved all the examples out of the README.MD and replaced them with links - I also moved the example links to be under the resource header they actually apply to.

While I was at it I found some spelling errors in the filenames and corrected those.
