JTreeTable

Hello,

I spent yesterday some hours and replaced TreeTableView with JTreeTable from the Swing Connection
(http://java.sun.com/products/jfc/tsc/articles/treetable2/index.html). 

There are some advantages by using this component:
+ it allows you to scroll the whole component horizontally. Not just the first column.
+ it allows you to rearrange all the columns (the first too)
+ it is model-based (!). We will be able to write a model for our Tasks. It will help us reduce memory consumption and 
  improve performance as we only need to maintain one tree of objects and a model (currently we have at least 4 levels of 
  objects: Tasks, TaskNodes, FilteredTaskNodes, VisualizerNodes and hundreds (OK, maybe dozens) of listeners).
+ we will have full control over the component and will be able to resolve some bugs

There are also some things now that are not implemented:
- sorting
- turning columns off/on

What do you think about it?

I could implement as the first step a component based on JTreeTable that behaves just like TreeTableView and uses NodeTableModel.
As the second step models for our views could be implemented. I wrote an issue against the openide module 
(http://www.netbeans.org/issues/show_bug.cgi?id=30447 Swing compatible TreeTableView) and asked for a model-based TreeTable.
