DESCRIPTION
Globally optimizes (parts of) the current tree.
The global optimization consists of two steps:
´Local optimization´
´K.L. optimization´
First step 1. is repeated until no further improvement is found.
Then step 2. is performed. If an improvement was found, it restarts at step 1. Otherwise the optimization stops.
