  - Progress bar for submission form.  Note this must be included within
  - the FORM element in the submission form, since it contains navigation
  - buttons.
  -
  - Parameters:
  -    step (int):  The current step.  One of constants in
  -                 org.dspace.app.webui.servlets.SubmitServlet.
  -    stage_reached:  The most advanced step the user has reached (i.e. the
  -                    most advanced step they can jump to)
  -                    One of constants in org.dspace.servlets.SubmitServlet.
  -                    It can also be "-1" - in this case, the progress bar
  -                    is in "Workflow Item" mode - i.e. the "license" and
  -                    "complete" stages aren't shown
  -    md_pages:       The number of pages used for metadata input/edit.
  - 				   Configurable on a per-collection basis
