Catching up with documentation before addressing other concerns.
Various changes included changes to Exception handling for StringCopyJob class.
Further debugging of SwingCopyJob class and changes to support a change in the SwingCopyJobListener interface.
Additional debugging of individual file and overall progress percentages as reported by a SwingCopyJob. Proper percentages are now reported (via registered SwingCopyJobListeners) when a job is cancelled or when resuming a copy operation. My appologies for suggesting (via Google Hangouts) a couple weeks back that the problem might have lied in the GUI.
Modification to GUI package's CopyJobListener implementation to permit the progress of the last file copy to be set to zero percent when the job is cancelled. The SwingCopyJob deletes the file fragment as part of the cancellation process and the code that updated the GUI wanted to see an existing file before updating the copyListModel. It now searches for an existing file OR previous pressence of the Path in the model.
