// followed by actual download details, something like:
// [ "English", { // download1 }, { // download2 } ]
// Which of course is not a problem for JavaScript, but is a problem for
// deserializing into strongly typed C# data structures.
// To work around this we wrapped encapsulated usual network requests,
// data transformation and desearialization in a sinlge package.
// To process downloads we do the following:
// - if response contains language downloads, signified by [[
// - extract actual language information and remove it from the string
// - deserialize downloads into OperatingSystemsDownloads collection
// - assign languages, since we know we should have as many downloads array as languages
