Update or create docstrings from many of the examples. This is part of
the gallery project, as the new docstrings will be the website visible
documentation for the example. Some changes are to use the main
phrase of ‘the file xx.py’ to include related files on the gallery page.
These are all documentation changes only.
This fixes a large number of white space errors in the examples/
directory.
When I upgraded Makefile to check the 'make style' on the examples
directory,
the output was hundreds of lines long. Currently, the output is
managable
and consists solely of "lines too long", as kv lines cannot be split.
This
commit touches an obscene number of files in trivial ways.
