[RFC] Packaging

Status:	draft

There currently can be a lot of problems related to python packaging and imports, due to the fact that we do not guide the users through the journey of creating a regular python package.

Directions

• Be as similar as possible as python standard behaviours.
  • see https://docs.python.org/3/using/cmdline.html#cmdoption-m
  • see https://docs.python.org/3/library/__main__.html
• The tutorial should be more explicit, and more step by step
  • first steps should use only one file, with a warning that says that you can't have local imports
  • more advanced steps should guide the user through the journey of creating a python package, OR integrating this file to its own python package.

Changes

• No detection of graph object anymore.
• bonobo run/runc/inspect/... would temporarily substitute the bonobo.run callable with something that use their own logic, and the graph used will be the one passed to bonobo.run(...).
• Question: how does additional parameters work?
