Fixed tests due to async var creation, plus minor stuff...
Fixed tests due to async var creation, plus minor stuff A variable is created synchronously but its data is get in background so tests have now to wait until the variable is ready before checking its state. VC should have a [] operator, it's a model feature. The new data provider interface implies that each call only ask for one range, this has been reflected in its parameters.

* Simple synchronous GET example:
* @code{.cpp}
* auto response = Downloader::get("http://example.com")
* std::cout << "Status code: " << response.status_code() << std::endl << "Data: " << response.data().toStdString() << std::endl;
* @endcode
*
* @note
* This is a quick and KISS implementation using QNetworkAccessManager isolating from Qt stuff (Signal/slots).
* This could be impemented with a different backend in the future.
