Dataset YAML schema

[danjjl]

Similarly to algorithms, datasets should be listed in dataset.yaml entries.
The schema for datasets should be produced. It can be based on the algorithm schema.

It should also include statistics on datasets, e.g.:

• Number of subjects
• Number of seizures
• Avg recording duration
• EEG Montage
• Total hours of recording

Several options seem possible:

• DatasetJSON (as defined by CDISC) -- No json.schema
• Based on CIFF -- no definition of th number of subjects, recording variables, ...
• Based on BIDS dataset_description.json -- very little information in the file
• Schema.org Dataset definition -- No json.schema, lack of variables, still might be the most commonly accepted solution as it seems well accepted
