TaskProgressUpdate class
A progress update
A successfully downloaded task will always finish with progress 1.0
TaskStatus.failed results in progress -1.0 TaskStatus.canceled results in progress -2.0 TaskStatus.notFound results in progress -3.0 TaskStatus.waitingToRetry results in progress -4.0
expectedFileSize will only be representative if the 0 < progress < 1, so NOT representative when progress == 0 or progress == 1, and will be -1 if the file size is not provided by the server or otherwise not known. networkSpeed is valid if positive, expressed in MB/second timeRemaining is valid if positive
Use the has... getters to determine whether a field is valid
