Yaml-interface
Every opentox plugin should adhere to the following YAML (http://yaml.org/spec/cvs/current.html) syntax for predictions:
id: 'id'
prediction: 'prediction'
confidence: 'confidence'
[...]
where 'id' is an alphanumeric identifier, 'prediction' and 'confidence' are either discrete or continuous values, depending on the prediction type (classification or regression).
[...] denotes optional information (key: value pairs).
