This patch attempts to improve the consistency of the docstrings by making the following changes: - Rewraps all docstrings to a 79-character column limit. - Adds a full stop at the end of every docstring. - Removes any spaces after the opening triple-quotes of all docstrings. - Sets the hanging indent of multi-line docstrings to 3-spaces. - Ensures that the closing triple-quotes of multi-line docstrings are always on a new line indented by a 3-space indent.
