disable Sensitive Detector for Spice (SiLi), fixed bugs in segment naming...

The SensitiveDetector was only used in SPICE and S3 for "historical reasons".
- I disabled it for SPICE, (next thing for the S3)
- Fixed a naming bug
- Filled the Tree for the first time, I still need to check one or two things to make sure everything is ok
- From now on the convention for counting sector/ring in the spice project start from "0"
