Introduce the initial project structure for gitcloak, a Python-based private frontend for GitHub repositories. Key changes include:
- Added .gitignore to exclude virtual environment, bytecode files, and cache directories.
- Added LICENSE file using the MIT License.
- Created a basic `pyproject.toml` with project metadata and dependencies.
- Implemented Flask-based application to render repository structure and file contents.
- Added `Git` class to handle interactions with remote GitHub repositories using Dulwich and requests.
- Included HTML template for displaying repo content.
- Created sample `test.py` for testing Git class methods.
This setup enables foundational project functionality and establishes a clear structure for further development.
