Refactor: Create Automatic Project Documentation

**Description:**
Set up tools for automatically generating project documentation from docstrings and module structure.

**Acceptance Criteria:**
- Set up Sphinx with autodoc for Python documentation
- Configure dependency graphs using pydeps
- Create a basic documentation structure with introductory content
- Add build scripts for documentation generation

Start by inspecting the Python package and module structure, then review how Sphinx autodoc and pydeps can represent it. Set up the documentation structure, dependency-graph configuration, and build scripts; done means introductory documentation builds successfully and reflects the project modules.
