Chameleon: A Reconstruction package for a KM3NeT detector
  In this note we describe the Chameleon software we developed for the event reconstruction of KM3 detector. This software package's developement started as a standalone application before the endorcement from the KM3NeT consortium of the SeaTray software framework, but it was adapted to it on the course.   Chapter 1 outlines the techniques we developed for the pattern recognition and the track fitting.   In Chapter 2, we demonstrate the performance of the Chameleon Reconstruction.
