+/**
+ * @brief manages updates for Mod Organizer itself
+ * This class is used to update the Mod Organizer
+ * The process looks like this:
+ * 1. call testForUpdate() to determine is available
+ * 2. if the updateAvailable() signal is received, allow the user to start the update
+ * 3. if the user start the update, call startUpdate()
+ * 4. startUpdate() will first query a list of files, try to determine if there is an
+ * incremental update. If not, the user will have to confirm the download of a full download.
+ * Once the correct file is selected, it is downloaded.
+ * 5. before the downloaded file is extracted, existing files that are going to be replaced are
+ * moved to "update_backup" on because files that are currently open can't be replaced.
+ * 6. the update is extracted and then deleted
+ * 7. finally, a restart is requested via signal.
+ * 8. at restart, Mod Organizer will remove the update_backup directory since none of the files
+ * should now be open
+ *
+ * @todo use NexusBridge
