perspective.py v0.1.1

I forgot the fact that in Python, dots are used for importing packages from child directories hence package names cannot include dots. Therefore I've updated the code to make the package name perspective yet keep the PyPI name as perspective.py.

Now you can import perspective.py as follows:

from perspective import Client, Attributes

Furthermore, you can still install the package by the following command:

python -m pip install --upgrade perspective.py
