Consider turning code directory into small package

[matthewfeickert]

As the Python code that is in the code directory has dependencies on itself it you might consider turning it into a very very small package instead. This would both make the maintenance and connections of the code much easier to understand but it also frees you from having to manually manipulate PYTHONPATH (which is annoying and prone to error) or from keeping you only working inside the code directory (as PYTHONPATH places the cwd on it by default in the same way PATH does).

Also, use of

from some_package_name import *

should be avoided basically at all costs. This destroys any use namespaces bring to software.
