ExpVideoConfigQuality Class
Video configuration frame showing webcam view at right and instructions for checking video quality for preferential looking setup at left, with pictures. Content is hard-coded for preferential looking requirements and images; this frame can serve as a template for other applications (e.g., verbal responses, where we might care less about lighting but want to generally be able to see the child's face) or can be generalized to show an arbitrary set of instructions/images.

eventTimings
The base class does not define any data to save to the server. It does, however, capture some basic event timing data. (such as when the user clicks the "next" button)
This section slightly breaks YUIDoc conventions- rather than being a literal guide to using the code, the "parameters" here are abstract descriptions of what data is captured.
Each frame that extends ExpFrameBase will send an array eventTimings
back to the server upon completion. This array is an ordered list (oldest
to newest) of every EVENT that happened during the frame. Each event is
represented as an object with at least the properties
{'eventType': EVENTNAME, 'timestamp': TIMESTAMP}. Frame-specific events
may define additional properties that are sent.
Parameters:
