[File restructuring]Move project files to repository root

[brylie]

Several files were added to the project, probably by Cookiecutter Django, in a sub-directory, such as the LICENSE and .gitignore files. It is conventional to keep these files in the repository root.

It might be simpler to move all of the project files, keeping the sub-structure, to the project root.

Task

• Move all project files under the cbv3_django_prototype directory to the repository root

Hold until #43 is complete.

Could be completed with #31 and #50.

@lpatmo you are assigned to this one. I've just removed the hold tag.

This looks like it was addressed by #99.
