Currently, the script generates both model file formats (.pb and .model). The TensorFlow model .pb
file will not change again, while the native .model file format will be changed timely especially in current
early stage.  It is not good to generate .model file here (see more detail in my patch 1 commit log). 

So, a new script (my patch 1) is added to generate the .model file. The above script is no longer needed to
generate .model file. 

For me, 'generation' means the dump of .model file, while 'saving' means the dump of .pb file.

thanks, will do it.
