Add ability to filter aggregate data

[SeanCena]

A very very minimal edit, but it would allow users to get aggregate data by country_code, province, etc. by adding a filter as a GET parameter. GET /api/v2/latest?country_code=US would solve #108 , for instance.

I really like the way this was solved, nicely done. This should probably be documented in the README.md under the /latest endpoint :).

Also, not a 100% sure if /latest should be responsible for the aggregation. Maybe it should instead be moved to /locations, and be put under “aggregated” or “latest” top-level? What do you think??

How is about testcases?

[ExpDev07]

@gribok that - i do not know XD

[SeanCena]

Not sure about testcases. I'm not really sure what you mean by aggregated or latest top-level, would you mind explaining in more detail? (Sorry if these are really basic things I should know as a developer, I'm quite new to all this)

[ExpDev07]

Like this:

/v2/locations?country_code=US

returns

{
  "latest": {
      "confirmed": 100000,
      "deaths": 4000,
      "recovered": 70000
  },
  "locations": [
  ]
}

"latest" being the sum of "latest" from all the locations returned (aggregated). Not sure whether we should call it latest or aggregated though.

All you do is basically move your code from latest() over to locations() in locations.py with some additions.

And it's okay aha @SeanCena

[ExpDev07]

Very nicely done! Could you perhaps rename it to "latest" instead? I think overall it would make more sense given that's what it's called inside the locations, then I'll go ahead and merge.

[SeanCena]

Thanks, I moved the latest() code to locations(). For now, I put the aggregate data under "aggregate". Also, one of the side effects is that you can now pass any attribute (not just country_code) as an argument to /locations, which I just realized includes the double-underscore attributes of the timelinedlocations class. Might be a security issue, idk? Other than that, everything seems to work fine. make tests fails because there is no __main__ module apparently.

In response to your new comment, yes, I will rename it to latest.

[ExpDev07]

Thanks a lot! Looks good. Merging.
