add Grouper permission role hierarchy visualization

For groups that are roles, in the existing visualization screen, there should be a submenu to be able to visualize role hierarchies.  arrows from roles to the roles whose permissions they absorb

e.g. from Superadmin -> Admin

For folders, in visualization, have a visualization option in the visualization screen that allows visualization for all roles in that folder (and subfolder).  find groups which are also roles in one query.
