    371371Tasks have start and finish dates.  We may want to be able to set these explicitly for individual tasks.  If no finish date is specified, the finish date is derived from dependencies.  If there are no dependencies, the task is assumed to finish on the milestone date.

    373 
     373An IProjectTask has the following properties:
     374
     375 id:: Numeric ID (Inherent in Trac)
     376 work:: Man-hours of work to complete task
     377 risk:: Relative risk.  An integer from 1 to 100.  How likely it is that ''work'' is accurate.
     378 priority:: Relative priority.  An integer.
     379 percentComplete:: How much of ''work'' is done?
     380 resource:: Name of resource assigned to this task
     381 assignedStart:: An explicit constraint on when the task must start (a date)
     382 assignedFinish:: An explicit constraint on when the task must finish (a date)
     383 computedStart:: The result of scheduling this task based on constraints.  Equals ''assignedStart'' if that field is set.
     384 computedFinish:: The result of scheduling this task based on constraints.  Equals ''assignedFinish'' if that field is set.
     385 dependencies:: A list of other tasks (by ''id'') and the dependencies of this task on them.
     386
     387''assignedStart'' and ''assignedFinish'' are likely mutually exclusive (that is, only one can be set).
     388
     389'''Do we need an ALAP/ASAP choice on individual tasks?'''
     390
     391Each dependency specifies:
     392
     393 task:: The ID of the task this task depends on  (I'd really like a better name here.  ''parent'' is wrong. ''origin''? ''other''?)
     394 type:: Dependency type (FS, SS, SF, or FF)
     395 lag:: Offset of this task's anchor relative to the anchor of ''task''. Whether the ''anchor'' for the dependency is the start or end of the task depends on the dependency type.  For example, if Task B has a FS dependency on Task A with a lag of 1 day, then Task B starts 1 day after Task A finishes.  Or, if Task B has an SS dependency in Task A with a lag of 1 day, then Task B starts 1 day after Task A starts.
