   *  initAPI   : 'string added to the URL to initialize the API',  // optional: the string must end with a parameter pointing to the video id (e.g. "&player_id=")
   *  embedOpts : { flashvars: {}, params: {}, attr: {} },          // optional: add any required flashvars, parameters or attributes to initialize the API
   *  // video startup functions
   *  init      : function(base, vid, index){ }, // optional: include any additional initialization code here; function called AFTER the embeded video is added using SWFObject
   *  // required functions
   *  cont      : function(base, vid, index){ }, // required: continue play if video was previously played
   *  pause     : function(base, vid, index){ }, // required: pause ALL videos
   *  message   : function(base, data){ },       // required for iframe: process data received from iframe and update the video status for the "isPlaying" function
   *  isPlaying : function(base, vid, index){ }  // required: return true if video is playing and return false if not playing (paused or ended)
   * }
   *
   * Function variables
   *  base (object) = plugin base, all video values/functions are stored in base.video
   *  vid (string) is the ID of the video: vid = "asvideo1"; so jQuery needs a "#" in front... "#" + videoID option default ("asvideo") + index (e.g. "1"); each video matching a service will have a unquie vid
   *  index (number) is the unique video number from the vid (starts from zero)
   *
   *  var list = base.video.list[index]; list will contain:
   *   list.id = vid
   *   list.service = service name (e.g. 'video', 'vimeo1', 'vimeo2', etc)
   *   list.selector = 'jQuery selector' (e.g. 'video', 'object[data-url*=vimeo]', 'iframe[src*=vimeo]', etc)
   *   list.panel = AnythingSlider panel DOM object. So you can target the video using $(list[index].panel).find(list[index].service) or $('#' + vid)
   *   list.status = video status, updated by the iframe event listeners added in the video service "ready" function; see examples below
