13* order of SEGMENTs and STRANDs in LOOPS:
14  * normal loops always start and end with a SEGMENT
15  * root-loop:
16    * version 1+2 ended with a strand
17    * version 3 starts with a strand (the fixpoint strand)

19* angles
20  * version 1 only DELTA
21  * version 2 had DELTA and DELTA_IN (loop->strand-angle (rootside) and reverse strand<-loop-angle (outside))
