RecoveredRegion class

A mixture between BaseRegion and DownloadableRegion containing all the salvaged data from a recovered download

How does recovery work? At the start of a download, a file is created including information about the download. At the end of a download or when a download is correctly cancelled, this file is deleted. However, if there is no ongoing download (controlled by an internal variable) and the recovery file exists, the download has obviously been stopped incorrectly, meaning it can be recovered using the information within the recovery file.

The availability of bounds, line, center & radius depend on the type of the recovered region.

Should avoid manual construction. Use toDownloadable to restore a valid DownloadableRegion.
