Description of problem: Users would have an easier time if there was context dependent right click functionality. If you right click on a node, you should see and learn all the functions associated to that object. Currently, for a node those would be 'edit', 'manage fencing', and 'delete'.
In addition, users would have an eaier time id there was a context-dependentdouble-click function available that would open a properties dialog box. For example, double clicking node "foo" would open the Edit Node Properties dialog box.
