HEAD
lonstatistics.pm:Removed package variable @SelectedSections.
Added &get_selected_sections
Added §ion_and_enrollment_description to provide a brief
description of those students selected for statistics work
(hopefully this descriptive line will make it in to bug reports).
Added §ion_and_enrollment_description to all statistics pages
Replaced use of @SelectedSections with &get_selected_sections in statistics
pages.
