API method to extract infos per countries

[Samy Pessé]

Something like:

GET /:website/countries

Parameters

It should accept the following query string parameters:

Name	Type	Description
start	Date	To query a range (default: none)
end	Date	To query a range (default: none)

These parameters should be common and normalized for almost all GET methods.

Results:

I think we should normalize the format of results for "pies", instead of having a different format for each (countries, platform, type):

{
    "list": [
          {
                  "id": "fr",
                  "label": "France",
                  "count": 1000,
                  "unique": 900 // Not sure it can be easily done, but it'd be awesome
          }
          ...
    ]
}
