multiple dependency management systems

[tngTUDOR]

For the moment, this repo has:

• setup.py with install_requires
• requirements.txt
• Pipfile

each has a different "design" intention [at the higher Python world level I mean]

for BONSAMURAIS org, we might need to settle which one we preferr.

Options could include:

• only setup.py with install_requires
• setup.py reading deps from requirements.txt
• requirements.txt being empty and only setup.py install_requires being the source of truth
• Pipfile being a source of truth.

The real issue, is that having multiple files configuring dependencies makes it confusing. The current design of the repo is to produce a distributable package, so a setup.py is necessary.

As for requirements.txt and Pipfile, they are convenience to ease the creation of environments (production, testing, developing).

I created this issue here so that we can agree on a single system, and provide guidance on further BONSAMURAIS practices.
