Module contents
DocStrings in an __init__ file will be written to the Module Contents section of auto-code documentation
generated by Sphinx. In our guide we also list the module contents before the submodule. This is not the default
but can be generated with autodoc using the –module-first option. Or, of course, you can also manually edit the
rst file for the module.
This __init__ file added to ensure that py_template is seen as a sub-package for usage with setup options like
package_data={} constructs.
