Delayed match-to-sample task.

A sample stimulus is shown during the sample period. The stimulus is characterized by a one-dimensional variable, such as its orientation between 0 and 360 degree. After a delay period, a test stimulus is shown. The agent needs to determine whether the sample and the test stimuli are equal, and report that decision during the decision period.
