// this is a program for converting a model file to a C source
// so that you can integrate the model data into your binary.
// usage)
//   First, convert the model file into a C source by this program.
//     ./a.out < model > modeldata.c
//   then, complile and link.
//   In your main program, use
//     model.load_from_array(me_model_data);
//   instead of 
//     model.load_from_file("model");
