Two GUI questions

1. What is a good way to put durations (times) into the tasks in the
GUI? I think we need to enter them as a set of parameters for a 
distribution. The default should be a fixed distribution: the _time_ for 
the task. Then a PERT distribution: three times. Possibly, later other 
distributions. But, how do we enter a time? It will be too much to ask 
for days and hours and minutes and seconds always. One possibility is to 
set a time scale for the project: days, weeks, hours. Then the default 
is to ask for times in the project _time scale_.

2. How should we specify time-dependencies. That is, answer the 
questions: what activities must be done before this one? What activities 
must be done after. I think of being able to specify this within the 
dialog to add or modify a task and also from a menu. Is this sensible?

You will see that I have not a well-formed concept of what the GUI 
should look like. If I can develop one, I will try to write some code. 
That, at least, may give someone else the opportunity to do better.
