Plan with Gantt, PERT and sprints

1. Gantt: drag a bar to move a task, pull its edge to change its duration.
2. Dependencies: in a task, set which tasks it depends on; PERT then computes the critical path and slack.
3. Sprints: create a two-week sprint and drag tasks into it to track the workload.
4. WBS and PBS: break the project down into work packages and products.
