body: <p>My objective is to build a check box node tree with the following features .</p>
  
  <p>Nodes :
              There will be 2 types of nodes all over the tree .
              <p>1 . Parent Nodes</p>
              <p>2 . Child Nodes</p>
  All the nodes are check box nodes .
  The parent nodes need to have an additional folder like icon , in addition to the check box.</p>
  
  <p>And all the check boxes must be editable
  More than one check box must be checkable at a time . </p>
