[jdom-interest] Filtering comments

Here's how I'd do it:

In the latest CVS, the factory impls have an addContent(Parent, Content) 
method called to add the content to the parent.  Subclass the default 
factory, override addContent() so if the Content is a Comment, the call 
just returns without doing the add.  Then pass your factory to the 
builder.  You could do this trivially using an anonymous inner class.
