ImportError: No module named 'hidparser.UsagePages' after running example/mouse.py

[float-tw]

First I install hidparser with following command
$ python3 setup.py install
then trying to run example/mouse.py get following error
Traceback (most recent call last): File "mouse.py", line 1, in <module> import hidparser File "/usr/local/lib/python3.5/dist-packages/hidparser-0.0.7-py3.5.egg/hidparser/__init__.py", line 10, in <module> ImportError: No module named 'hidparser.UsagePages'
But I can import hidparser and hidparser.UsagePages before run example.
When I unzip the egg file 'hidparser-0.0.7-py3.5.egg', there are no hidparser/UsagePages folder.

I try to add "hidparser/UsagePages" into packages in setup.py and it can fix this problem; however, I'm not familiar with setuptools. Is this correct way to fix it?
