\brief Factory for \ref KDUpdater::FileDownloader
This class acts as a factory for \ref KDUpdater::FileDownloader. You can register
one or more file downloaders with this factory and query them based on their scheme.
This class follows the singleton design pattern. Only one instance of this class can
be created and its reference can be fetched from the \ref instance() method.
