Tool to mark all missing attendance for a school as present

[ghachey]

It would be a great time saver to be able to enter attendance data in the following way. This is particularly useful for schools not too strong with data entry; a person in the central data office can simply input all the data in the fastest possible way for them.

1. Enter all the absences through the standard admin office feature (or Teacher Function)
2. Once al known absences are entered we know that everything else is a default of Present. A single click button to mark all remaining attendance data as Present for all missing attendance from first day of school (or last known attendance data entered) up to the point of operation (or last day of school if operation is execute beyond that date)

Currently we still need to mark each individual day's attendance and this is time consuming for the use case of supporting many schools with still weak technology skills.

This will need to be tested in the following scenario:

• No attendance data taken.
• No attendance data taken through teacher function but a few absences entered through admin office feature.
• Partial attendance data taken through teacher function (say a week late in attendance and some courses more then a week late).
• Partial attendance data taken through teacher function and some absences entered through the admin office feature.
