3.11 Dave Fletcher (see Problem 3.10) was able to determine
the activity times for constructing his laser scanning
machine. Fletcher would like to determine ES, EF, LS, LF, and
slack for each activity. The total project completion time and
the critical path should also be determined. Here are the activity
