Git LFS

Please consider using Git LFS in this project so that large asset files can be stored separately and be managed easily. Here is a sample config file for Git LFS in a Unity project:

https://github.com/SeedV/SeedCalc/blob/main/.gitattributes

3rd-party lincense

The "Unity-chan! Model" is a third-party asset released under its own license. Considering the copyright compliance, I'd suggest to add a README.md file to the dir Assets/Models/Unity-chan! Model. The file could contain the following info:

Unity-chan is an original character for developers provided by Unity Technologies Japan. It's released under the Unity-chan License.

MediaPipe is not the same case since its source code has already had its own copyright info.

Coding style

Assets/Scripts/Mediapipe/Test.cs

1. Which coding style are we going to follow for our own C# code? SeedCalc is following the Google C# Style. I'd suggest we do the same thing here.

2. Can Test.cs be put into a sub dir, such as /Assets/Scripts/Mediapipe/Examples?

3. It'd be better not to name it as Test if it is not a real unittest code.

Applied changes.

• Added .gitattributes to declare metadata for LFS as suggested.
• Added Assets/Models/Unity-chan! Model/README.md as suggested.
• Removed Assets/Scripts/Mediapipe/Test.cs. This file is meant for temporary use. It's only used to test importing the Unity plugin and no compile error is caused by the file, and I planned to remove it in a follow-up CL. Simply skip checking in this file.
