OPEN - task 14: Gradebook Monitor Report - Change Attendance Subreport 
http://github.com/maine207/aspen/issues/issues/issue/14
Updated the format definition to include the selected grade term in the
header. Also edited the attendance subreport and corresponding Java
source so that it shows counts of excused and unexcused records.

Still need to fix the subreport so that the bottom line of the table is
drawn in the report.
