Issue: Start API Documentation with Sphinx

Description:
We need to start creating the API documentation for the project using Sphinx. This documentation should provide clear, detailed, and easily navigable explanations of the available classes, functions, methods, and key components, along with usage examples and relevant code snippets.

Suggested Action:

1. Set Up Sphinx Documentation Structure:

   • Install Sphinx and set up the initial configuration.
   • Create the necessary configuration files (e.g., conf.py, index.rst) to organize the structure of the documentation.
   • Define the table of contents, starting with a basic overview, followed by sections for each key module or component.

2. Integrate Autodoc for Docstring Extraction:

   • Enable the Autodoc extension in Sphinx to automatically extract docstrings from Python code.
   • Ensure that each class, method, and function has clear, concise docstrings following a consistent style (e.g., Google, NumPy).
   • Document the parameters, return values, exceptions raised, and provide usage examples where applicable.

3. Document Key Components:

   • For each key class or function in the codebase, provide the following:
     • Description: A summary of what the component does.
     • Parameters: Detailed information about the expected input parameters.
     • Return Values: Explanation of what the function or method returns.
     • Examples: Code snippets to demonstrate how to use the component.

4. Ensure Cross-Referencing:

   • Use Sphinx’s cross-referencing capabilities to link related components, such as linking methods to the class they belong to, or referencing helper functions across modules.
   • Set up anchors within the documentation to make navigation easier for users.

5. Test and Review Documentation:

   • Preview the documentation to ensure all docstrings are correctly rendered.
   • Check that all links, cross-references, and code blocks are working as expected.
   • Make sure the documentation is clear, organized, and easy to navigate.

6. Additional Sections (Optional):

   • Consider adding an installation section, a contributing guide, and any other general documentation that may help new developers or users understand how to get started with the project.

Additional Notes:

• Sphinx will help generate clean, professional, and structured documentation, and its extensibility will allow for customization as needed.
• We may also want to use Sphinx extensions like sphinx-autodoc-typehints for automatic type hint extraction or sphinx-rtd-theme for a user-friendly layout.
