minor documentation changes/additions and addition of getPathnames method to FileCopier interface
Refactoring of FileManagement package's classes to support passing a list of Path objects to a copyPathnames method. Tests, as previously written, are passing but I'm now writing additioning tests to ensure proper functionality and to increase test coverage, which is now far too low.
Merge branch 'master' into FileManagement
Modified classes so copyPathnames method takes a Set<Path> rather than a List<Path>.
Extensive modifications to SwngWorkerBasedFileManagerTest JUnit test class and tons of debugging of SwingCopyJob class. Test coverage of FileManagement package is up to 71%. Need additional coverage but I need to get moving on the long-pathname copy support.
