The implementation includes:

Proper input validation and local caching in ~/.movement/public_data
Comprehensive unit tests verifying all functionality
An example file demonstrating typical usage patterns
Documentation explaining available datasets, parameters, and citations

Thanks for attempting to tackle this @demoncoder-crypto. We are experiencing a high volume of PRs at the moment, but we will get to reviewing this eventually.

Could you deal with the pre-commit and linting failures in the meantime?
You can do pre-commit install (needed only once), followed by pre-commit run -a in your development environment.

After that the checks should automatically apply to all commits you attempt.

Thanks @niksirbi for comments, I tried to fix pre-commit issues. Please let me know if they are up to expectation. thanks

Downloading file 'videos/rotating-mouse_eye-tracking_stim-uniform_video.mp4' from 'https://gin.g-node.org/neuroinformatics/movement-test-data/raw/master/videos/rotating-mouse_eye-tracking_stim-uniform_video.mp4' to 'C:\Users\Freiz.movement\data'.
The package gets stopped here and nothing happens then when i try sphinx build C:\Users\Freiz\AppData\Roaming\Python\Python311\Scripts\sphinx-build.exe -b html source build
Is there a way to fix this?
