  Added files:                 
    /bojangles	xmlFileFilter.java 

  Modified files:              
    /bojangles	Makefile MainWindow.java 
  Log:
  Figured out how to open an existing document and read it in as if the user were redoing it all over again (using some "borrowed code from treePopupMenuAddActionPerformed())
  
  Also added a file filter so we can only save/open .xml files (i'll add .gz capabilities later as i dont think its a priority right now)
  
  If you try to open an XML file, it only adds the root node now (a correlations NPE problem)
