/***********************************************************************
 * 
 *  This is InFileCreator, To creator the in-file for Ptolemy
 *          only for (d,p), (d,p), (d,d), or (p,p)
 * 
 *  It read a simple infile.in from reaction_setting file
 * 
 * -----------------------------------------------------
 *  This program will call the root library and compile in g++
 *  compilation:
 *  g++ InFileCreator.C -o InFileCreator `root-config --cflags --glibs`
 *
 *------------------------------------------------------
 *  The reaction_setting file is simple like:
 *
 *  206Hg(d,p)207Hg(1s1/2 0.000) 10MeV/u AK
 *
 *  the first is similar to usual reaction setting, the word AK is a
 *     short name for Optical Potential, user can put as many line as
 *     they like, Cleopatra can create the suitable infile.in for Ptolomy
 *
