Python packaging and installation

in setup.py file

for instance ::
    from distutils.core import setup
    setup(

      name = 'MyTools',

      version = '0.1.0',

      author = 'zhijia yuan',

      packages = ['oct'],

      author_email = 'zyuan@topcon.com',

      install_requires = ['NumPy >= 1.0.4'],

      )

after installation, the available import is related to the packages name::

    import oct #works

    import MyTools.oct #doesnot work

which means that the name MyTools just a top tag for your package, and oct is the real package name that you can import

if you have multiple packages, it would be more reasonable to keep the name and package name organized.
