More analysis shows that one reason for the adding memory is because some
singleton classes do not release corresponding resources when a workflow is
opened and closed. 

Classes we found so far:
1) Vector<JTree> _trees and Map<String, VisibleTreeModel> libraryModels in
LibraryManager class;
2) Vector<ViewPane> _viewPanes, Hashtable<TableauFrame, JPanel> _viewAreas,
Hashtable<TableauFrame, JComboBox> _viewComboBoxes in ViewManager class

These variables only add new elements when a new workflow is opened, but do not
remove elements when workflows are closed. Also these two classes hold
references eventually connecting MoMLParser. 

I add Aaron in the discussion since he is the original author of these two
classes. He might have useful feedback.
