These are classes that are copied from Eclipse and modified.  Hopefully they can be
removed at some point if the correponding Eclipse support gets more general.

- ResourceAndContainerGroup and ContainerSelectionGroup can now go away.

- FileSystemExportOperation - only exists because the FileSystemExporter is private, 
changed to protected.  No bug filed.  3.4M5.  15 Feb 08.


// When 237243 is fixed, the GridData and GridLayout can be removed
// (this bug is unlikely to be resolved)

ScollingWizardDialog has been contributed as part of bug 188724, this could be fixed in 
3.6 (I will probably need to do the work), the the ScrollingWizardDialog class can go away.
