11	/* The WORKFORCE SHIFT COVERAGE is an assigment problem that determines
12	the schedule of crew given available time and shifts.
13
14	The objective is to cover the available time given hourly demand with the minimum
15	number of crew members.
16
17	This is a set covering problem that is very common among finding crew
18	and shift allocations. Notice in the data section the workforce shift allocation
19	per day of the week.*/
