A subject represents a human being who is the subject of a record, ie the person wearing the headset during the record. A subject is a permanent object. It is stored on the hard drive and then synchronized to the EMOTIV cloud.
To associate a subject to a record, you must create the subject first, by calling createSubject. Then you must specify the subject name when you call createRecord. A subject is identified by his/her name.
You can call querySubjects to list the subjects already created for the current user.
