Add descriptions to figshare datasets

Here is the link to the google sheet with all of the figshare datasets. Each dataset must be given an appropriate description, a task that I will be overlooking. If you have any familiarity with the given datasets, please enter a description! Assigning everyone for now.

We first do the figshare links (#14), and once that is done, we come back to this issue.
