Error: No file called render_balls_so

Hi,

Thank you for open sourcing the code. It's a good work.

When running the code, I went into a problem. I ran python show3d_balls.py and got an error.

Traceback (most recent call last):
  File "show3d_balls.py", line 20, in <module>
    dll=np.ctypeslib.load_library('utils/visualization/render_balls_so','.')
  File "/anaconda3/lib/python3.6/site-packages/numpy/ctypeslib.py", line 155, in load_library
    raise OSError("no file with expected extension")
OSError: no file with expected extension

It seems that you forget one file?
