 A slightly more sophisticated implementation would track individual resource availability so that the schedule can account for vacations and such.
 
+An IProjectCalendar should provide the following methods:
+
+  startFromFinish(task,finish):: return the date on which ''task'' must begin to complete by ''finish''.  If ''task's'' work is more than a day, this accounts for weekends, etc. so ''finish'' - ''start'' may be more than ''task.work''.

+  startFromFinish(task,finish,resource):: return the date on which ''task'' must begin for ''resource'' to complete it by ''finish''.  If ''task's'' work is more than a day, this accounts for weekends, etc. so ''finish'' - ''start'' may be more than ''task.work''.  May account for ''resource's'' vacation, etc. in addition to the general work calendar.

+  finishFromStart(task,start):: return the date on which ''task'' will complete if started on ''start''.  If ''task's'' work is more than a day, this accounts for weekends, etc. so ''finish'' - ''start'' may be more than ''task.work''.

+Computing a schedule involves determining the ''computedStart'' and ''computedFinish'' for a set of tasks taking into account the dependencies between tasks and the resources assigned to those tasks.  Where the tasks do not have assignedStart or assignedFinish, the computed schedule prioritizes tasks to keep resources at or below 100% utilization.  However, assigned dates may force overloaded resources.  These overloads can then be reported and either manually resolved or resolved with a resource leveling module apart from the scheduler.
