Missing Expected regions where xray analysis is expected to be viable

[JordanMicahBennett]

There are many things one may learn from your work here with CovidNet, as it is robust work that will reasonably help to push/democratize Ai in a positive direction.

One thing of note, is that there are expected regimes for which xray/ct based techniques, be it by human or by ai, are expected to be viable. Unless I am mistaken, I did not detect that in the CovidNet paper nor the CovidNet/repository's readme file.

I think a similar section from the repository seen in issue 55 after title "Preliminary Conclusion", concerning expected constraints on testing/diagnosis, should be considered for CovidNet.

A quick snippet can be seen below:
