Test Programs: interactive test is necessary.

plot single dish spectra by sdplot + header=True or asapplotter.plot+asapplotter.print_header, and move between pages.
Check if you see header strings plotted in the same size and position in every page.

Put in Release Notes: No

Module(s): asapplotter, sdplot

Description: fixed a bug in asapplotter. asapplotter now prints header strings in every page.
