>Subject: [PATCH 2/2] Added data collection view
> (PerfDataCollectionView.java).
>
>This view is used to display the selected data files that will be compared
>when the PerfDiff action is invoked. To keep track of the selected files
>an object array is used, which is updated everytime a selection is made.
>An ISelectionListener is used to listen to selection events and
>update the view accordingly.
