Adding coding examples for Contact and ContactOption - v2 with signed commits

♻️ Current situation & Problem

When I was creating a contact for our application, I was unable to see coding examples. These added examples hope to clarify how someone might build and implement these features.

All of these changes were copied over from my previous pull request for signed commits.

@philippzagar: Here is my updated pull request for the other module! I am unable to request a review from you, but if you would be able to review it that would be great! I have copied over all of the changes that we discussed in the previous PR. You hadn't reviewed those, so that PR is still open so you can see how I changed the code according to your responses. Thank you so much!

[akanshyabhat]

@philippzagar I wasn't too sure what you meant by combining the examples - if this is not what you wanted please feel free to let me know!
