Auto bottom up

The bottom-up approach to planning goes from the specifics to general or, in other words, starts with the most detailed level.

Tasks will behave according to the following rules:

1. Parent in "auto bottom-up" adjusts automatically based on its children i.e.:
   a. start date of the parent = minimum of children's start dates
   b. end date of the parent = maximum children's end dates
2. If the parent in "auto bottom-up" wants to adjust dates of its children but superior element in WBS does not allow it, then the children may not be allowed to change start or end date.
