put branches on log, not tree. Redefine "2 levels"

[DizzyDogg]

i want the log to have the branch instead of the tree so that my required composition for a tree does not need to check its visible as well as composition. Something should NEVER be defined by their visible inventory ("Don't judge things based on their appearance").
now, when i look 2 levels deep, I should also check one composition level and its visible one level. That is still 2 levels deep.
The log should keep the branch forever until someone looks at the log. Then they will know it is there and can chop it off it they so choose.
