Refactor/add to pip

[OtacilioN]

Related to #1 I start this pull request with a refactor to make this lib as a python module to be imported in pip module manager.

List of implementations:

• Improve README.md with pip install module way
• Move files to project folder
• Add setup.py
• Improve gitignore file and prettify example

Since after this pull request we will already have a setup.py file and the module in the pip format, you can follow this tutorial to submit this module to pip manager.

Best regards, Otacilio Maia.
