Project gravity, general dataset

This is to store general lab data in a catch-all folder on golatsche.

Procedure for manually saving data

1. Do something in the repo folder (make files, etc.)
2. datalad save
3. datalad push --to github

The last step has been set up so it also pushes object data to ucloud.

See Shared/gravity/datalad/README.md for installation/setup instructions on your office computer, etc.
