+/**
+ * This is an especially interesting function. A naive reader might think that
+ * it returns this SmallVideo's "video" element. But it is much more exciting.
+ * It first finds this video's parent element using jquery, then uses a utility
+ * from lib-jitsi-meet to extract the video element from it (with two more
+ * jquery calls), and finally uses jquery again to encapsulate the video element
+ * in an array. This last step allows (some might prefer "forces") users of
+ * this function to access the video element via the 0th element of the returned
+ * array (after checking its length of course!).
