[Planner Dev] Duration Calculation

Hi all. I have a question really. I have checked out the latest code
from the gnome cvs server and have built and installed it and noticed
that the Work time for summary tasks calculation has been corrected to
be the summation of the work of the sub-tasks which makes complete sense.

However, I also noticed that the Duration calculation does NOT seem
correct, well to me at least. In my opinion the Duration should be
calculated by adding up durations of the subtasks which share a specific
resource (this will no doubt require using the unit to calculate
percentage of the work that a specific resource is assigned). Then after
doing that compare that total to the duration of each non associated
task and use the largest duration out of them all for the summary task's
duration.

Please let me know what all your inputs is on this. I have looked at the
code a little and see the new addition

mrp_task_manager_calculate_summary_duration()

in revision 1.18 however as the comments above the function denote it
ignores assignments.

Why is it ignoring the assignments? The reason this is problematic for
me is because the gantt chart uses the durations so that a visulazition
of the time needed for certain tasks can be seen. In this case it is
ignoring the fact that if a single resource is applied to two different
tasks the duration is going to be the sum of the tasks that resource is
assigned to, due to the fact that that one resource can't do both things
at once.

Well, anyways, let me know your thoughts on this.
