Make this a CookieCutter template

CookieCutter allows a repo to be used as an automatic template with text replacement, e.g. by allowing placeholder text like the project name.

Here is an example of a cookiecutter template for a python project

It works like this:

> cookiecutter https://github.com/audreyfeldroy/cookiecutter-pypackage                            

full_name [Audrey Roy Greenfeld]: My Name
github_username [audreyr]: somebody
project_name [Python Boilerplate]: supertest
project_slug [supertest]:
project_short_description [Python Boilerplate contains all the boilerplate you need to create a Python package.]: Just a test
pypi_username [somebody]:
version [0.1.0]:
use_pytest [n]: y
use_black [n]: y
use_pypi_deployment_with_travis [y]: n
add_pyup_badge [n]: n
Select command_line_interface:
1 - Click
2 - Argparse
3 - No command-line interface
Choose from 1, 2, 3 [1]: 1
create_author_file [y]:
Select open_source_license:
1 - MIT license
2 - BSD license
3 - ISC license
4 - Apache Software License 2.0
5 - GNU General Public License v3
6 - Not open source
Choose from 1, 2, 3, 4, 5, 6 [1]: 2

Which then creates a structure like:
