Guide Request: How to Code Reviews / Pull Requests

[bvhme]

As needed for #8

As per current contrib-guide:

• Style — identify discrepancies from this guide
• Potential Bugs — try to think about what might break
• Error Handling — if something external can cause an exception, how will the user experience it?
• Efficiency — will things scale and still be responsive?
• Readability — can you understand what's going on?
• Requirements — does the commit fulfill the requirements of the ticket
• Does the code do what is should do -- run the code and see if it does not do weird things like downloading the internet.
• Check that code endpoints and parameters are sufficiently tested -- there should be minumum amount of health checks
• Debug mode / health checks -- Common security mistakes should be checked.
• Decide for yourself if you could maintain and bugfix the code you see

I believe this issue still applies due to the new PR #21
