[New Navigator] Remember selection status of leaves of the navigation tree.

Remember selection status of leaves of the navigation tree.

Example: 
Attribute "is_patient" has two possible values "true" and "false". We might 
only select "is_patient" with value "true" at sometime to filter out 
annotations. This means only the leaf "true" of "is_patient" is selected and 
the leaf of the other value is not selected. While eHOST call repaint() 
function or others to regenerate this tree, eHOST need to remember the previous 
selection status of these nodes.
