Detailed Description

Collects information on stand level for each tree species.

Call clear() to clear the statistics, then call add() for each tree and finally calculate(). To aggregate on a higher level, use add() for each StandStatistics object to include, and then calculate() on the higher level. Todo-List for new items:

add a member variable and a getter
add to "add(Tree)" and "calculate()"
add to "add(StandStatistics)" as well!
