New Development: Yes

JIRA Issue: Yes (CAS-1822)

Ready for Test: Yes

Interface Changes: Yes

What Interface Changed: added "- page" (inactive) and "+ page" buttons to the toolbar

Test Programs: try "+ page" button

Put in Release Notes: Yes

Module(s): asapplotter & sdplot

Description:

  1. "- page" (inactive) and "+ page" buttons to the toolbar to enable

multi-page plotting. Currently "+ page" is only supported.
