Resolve an import error in pip installation

[BECATRUE]

To resolve the error, I implemented as follows:

• Make the qiwis directory and move qiwis.py in it. The structure is similar to iquip repo's.
• Modify the qiwis command to qiwis.qiwis:main.

Also, I made a pre-release for testing if it works well. Please check the following command runs correctly.

$ pip install git+https://github.com/snu-quiqcl/qiwis.git@v2.0.2-alpha
$ qiwis  # probabily there is no setup.json, it will cause an error, but the command should be recognized well
$ python
>>> from qiwis import qiwis
>>> qiwis.BaseApp
<class 'qiwis.qiwis.BaseApp'>

The pre-release will be removed after this PR is completed.

The pip installation and the commands work as well in my machine! How does this solve the problem?? Should it be a package, not a flat module? If so, let's make an __init__.py and from qiwis import * in it.

Honestly, I don't know exactly why, but I guess that the files we want to distribute should be located in a package, and we should clarify the package name into packages of setup.py.

In Writing the Setup Script description, it shows how to release a package, not only a module.

If so, let's make an __init__.py and from qiwis import * in it.

Did you intend from .qiwis import *? I think it's a good idea!

In this case, however, python -m qiwis.qiwis -s examples/setup.json causes an warning due to an import procedure as follows.

RuntimeWarning: 'qiwis.qiwis' found in sys.modules after import of package 'qiwis', but prior to execution of 'qiwis.qiwis'; this may result in unpredictable behaviour

Then, I suggest two solutions:

1. Use python qiwis/qiwis.py -s examples/setup.json instead of the original command.
2. Make __main__.py in qiwis package and write as below. Then, we can run it by python -m qiwis -s examples/setup.json.

   from .qiwis import main
   main()

How about this example?

Oh, I will check the example!

Oops I'm sorry it's a legacy module distutils.

@BECATRUE Please find out my solution here! You can try:

1. uninstall your qiwis by

   pip uninstall qiwis

2. install qiwis from setup-test tag by

   pip install git+https://github.com/snu-quiqcl/qiwis.git@setup-test

Does this work for you as well? cf) I use python3 -m pip instead of pip.

It works so well! As you think, I think releasing only the package looks neat. Then, may I modify this like your test branch?

Good! I only changed the packages to py_modules in setup().

A lot of parts have changed, so I made a new PR. Please come to that PR.
