cookiecutter text shouldn't be in generated repo

[hackalog]

this text

Now would be a good time to initialize a git repo; i.e.
>>> git init
>>> git add .
>>> git commit -m 'initial import'
>>> git branch easydata    # tag for future easydata upgrades

doesn't make sense in a generated repo, as it's already checked-out.

Note, this could likely be moved to a cookiecutter conditional in the .post-create-environment.txt
