// So, let's first clarify the structure of Chaoxing Student Study Page
// A course is made up of mulitple chapters
// A chapter is made up of mulitple cards, saying a multi-media card and a unit test card
// A card is made up of multiple jobs, saying two video jobs and a ppt job
// When a video job is finished, finishJob() would be called on MoocPlayer,
// which calls proxy_completed(),
// whick calls ed_complete(),
// which calls JC.completed on card iframe,
// which emits an completed event,
// which trigger unlock(),
// which calls onReadComplete() on the top window
// When a ppt job is loaded, uParse() would be called
// which calls unlock()
// onReadComplete() then calls onReadComplete1() to pull updated chapter list from the server
// and calls jobflag() to figure out how many jobs remaining to finish
// jobflag() looks in card iframe for .ans-job-icon as total jobs and .ans-job-finished as unfinished ones.
// ppt jobs doesn't count for they don't have .ans-job-icon or .ans-job-finished
// Generally speaking we only need to handle video jobs
// However Chrome blocks Flash. :facepalm:
