Python Docstrings

Python code documentation shall adhere to the PEP257 and numpydoc conventions.

The following are further recommendations:

• Each module should have at minimum a description and a Use section.

• Each function/method should have at minimum a description, Parameters (if necessary), and Returns (if necessary) sections.

When a new module is added to the repository, make sure to add the module to the appropriate docs/source/*.rst file, so that the API documentation can be part of the automated documentation build.
