// *********************************************************
// PROGRAMME SIRE.C
// In this version of the code only one turn tracking.
// Code of A. Vivoli
//
// Revival of the code by F.A.
// Start working on the code --> May 2014
// Changes:
// 1. Use input file to define parameters (June 2014)
// Add the input file as an input argument when executing
// 2. One code for 1-turn or multi-turn with flag in the parameters file
