Merged requested to merge feature/global_incident_rates into master
Closes #279 (closed)
This MR links the
geographic_cases parameter with the API comming from a WHO database, instead of having a user input, via a server-side API -
CasesData. It gets at first the common name for the country in question (via a REST countries API) and then calculates the average value from a WHO database available here.
Added a validation for data that is not up-to-date - if any of the days has a
0 value in the
New_cases field (from the database), it means that the dataset is (still) not updated, therefore we don't provide the
7-day rolling average value.
