new package io.py which should contain all import and export routines written by ourselves, such as reading old PILOT phase and location information file; implementation of the readPILOTevent function; new routines in utils: createArrival will be split into two functions: createPick and createArrival; also planned: createOrigin, createAmplitude and createMagnitude as well as giving createEvent functionality
