Add checkbox tree example 
--------------------------

                 Key: RF-1372
                 URL: http://jira.jboss.com/jira/browse/RF-1372
             Project: RichFaces
          Issue Type: Task
            Reporter: nayan j
             Fix For: Future Versions


Creating a rich:tree with checkbox at each node is bit difference from creating a regular tree and poses new challenges. I request you  to add an example for it.
Here is a list of challenges that make this use-case different:
1. Requirements to use a:support inside treeNode to handle click events (e.g. selecting nodes in subtree of selected checkbox or unselecting parents of a node when checkbox is unchecked).
2. Alignment issues that originate from usage of checkbox and text in different font-sizes when used together in treeNode.
3. Default mouse-over effects of rich:tree components makes the tree look ugly as treeNode now comprises of two parts. It is not clear which css style needs to be overridden to change these effects.
4. It is not clear when events get fired due to clicks at different locations in the tree. It will be nice if the example could show how to turn off these events if desired by the developer. 

There are several posts in richfaces forum discussing issues with using checkbox tree.
