Port to python3, large code cleanup * Fixed command line for cosmotool * Fix path * Dump command line is log file * Fix important typo * Modify paths for example * Fix path again * Use an explicit constructor * Change file to open (python 2->3) * python3 fix for xrange in periodic_kdtree.py * Fixed index for Np, numPart, numZones, numZonesTot, partID, zoneID in catalogUtil.py
