[kplato] the source tree

[John D Lamb]

I had a look at this. The expected duration of a Project will need to be
calculated by PERT/CPM but the expected duration of a task will be
calculated from information about the task itself. I'll see if I can put
together some code this week for how I'd try this.

It might be useful to make this a little more abstract by (eventually)
using a function like KPTProject::getDuration( int d =
DurationType::expected ). Then the code could be reused to calculate
(say) getDuration( DurationType::optimistic ), or getDuration(
DurationType::random ) for Monte Carlo
estimates of the distribution of likely project times.

JDL

PS Where do you get KDOC from? I think I prefer doxygen but kplato ought
to have kdoc support.
