add ability to append data to all trials #136

Closed jodeleeuw closed 9 years ago

jodeleeuw commented 9 years ago

Often it's necessary to append some kind of data to all of the trials. For example, a subject number or condition assignment. This should be easier. Perhaps:

jsPsych.data.addProperty({
  subjectid: 2,
  condition: 'left-handed'
});

List can be arbitrary length with arbitrary key: value pairs. Will update all of the data currently stored, plus add it to any new data that comes in (allowing the method to be called before or after experiment.

Related to this: remove the append_data parameter from dataAsCSV and localSave.
