Prevent Users to Submit Their Timesheet If Daily Required Hours are not Completed

Following script uses WorklogHelper service to get daily required work hours and daily actual work hours of the user for the timesheet period and checks the differences for totals. If user is submitted less than required work hours, it rejects timesheet submission.
