Fixed the One-Per-Day DoubleAllocation Bug.
The bug was that the program allocated the same 2-hour
slot more than once per day.
It is now fixed.
However, I notice another bug. In the screen shot above,
notice that, although LR100 was not full, the program
went ahead to LR200 ("Room-Not-Full Bug").
To Do:
Fix the Room-Not-Full Bug above.
