Started work on register report.
Checking in progress on register report query
Checking progress on register-report. Looks right for small register
reports, but looks like it might be wrong for larger ones. Need to be able
to visualize the results though, so time to work on front end.
Added web handler for register report
Added register report to front end.
Added present-register to back end to transform data prior to sending.
Added link to register report from balance reports.
