Summary of Changes

Hello @ChristopherRabotin, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on refining the ANISE tutorial that covers the use of frame kernels and text planetary kernels. The changes aim to make the tutorial content more precise, grammatically correct, and easier to follow for users. Additionally, the documentation's navigation has been enhanced to ensure that information regarding Euler parameter ANISE (EPA) kernels is more readily discoverable, ultimately improving the overall user experience and clarity of the ANISE documentation.

Highlights

• Tutorial Refinement: Improved grammar, spelling, and clarity throughout Tutorial 05 to enhance readability and understanding of ANISE kernels, including more precise descriptions of Euler parameters and version compatibility.
• Documentation Structure: Added a new navigation entry in mkdocs.yml to explicitly list 'Euler parameter ANISE (EPA) kernels' under tutorials, pointing to the existing Tutorial 05 for improved discoverability.
• Content Enhancement: Introduced a new subheading 'How to build EPA files' within Tutorial 05 to provide clearer guidance on converting Frame Kernel (FK) files into Euler Parameter ANISE (EPA) format.

Code Review

This pull request updates the ANISE tutorial on frame and planetary kernels with several grammatical fixes, typo corrections, and formatting improvements. It also adds a new entry for the tutorial in the documentation's navigation index. The changes enhance the clarity and correctness of the documentation. I have one suggestion regarding the new navigation entry to avoid redundancy.

[gemini-code-assist]

While adding a separate entry for 'Euler parameter ANISE (EPA) kernels' improves discoverability, it also creates redundancy in the navigation menu as it points to the same tutorial as 'Planetary constant kernels (PCK)' on the preceding line.

To create a cleaner navigation experience, consider combining these two entries into a single, more descriptive one. This would involve replacing both lines 98 and 99 with something like:

          - Custom Kernels (PCK & EPA): anise/tutorials/Tutorial 05 - Using frame kernels and text planetary kernels.ipynb
