/**
* jspsych plugin for categorization trials with feedback and animated stimuli
* Josh de Leeuw
* updated December 2013
*
* display a sequence of images at a fixed frame rate then give corrective feedback based on the subject's response
*
* parameters:
* stimuli: array of arrays. inner array elements are paths to images. each inner array is a set of frames
* that will be displayed as an animation sequence.
* key_answer: array of key codes representing the correct answer for each stimulus.
* text_answer: array of strings representing the label associated with each stimulus. optional.
* choices: array of key codes representing valid choices that can be made. other key responses will be ignored.
* correct_text: HTML string to show when correct answer is given.
* incorrect_text: HTML string to show when incorrect answer is given.
* NOTE: for both of the above, the special string %ANS% can be used. The text_answer associated with
* the trial will be substituted for %ANS%.
* reps: how many cycles through the animation sequence to show. -1 will show until response is given.
* allow_response_before_complete: if true, the subject can give a response before the animation sequence finishes.
* timing_feedback_duration: how long to show the feedback for.
* timing_post_trial: how long to show a blank screen before the next trial.
* frame_time: how many ms to show each individual image in the animation sequence.
* prompt: HTML string to show when the subject is viewing the stimulus and making a categorization decision.
* data: the optional data object
