  17  Function: Swiff
  18      creates a flash object with supplied parameters.
  19  
  20  Arguments:
  21      source - the swf path.
  22      properties - an object with key/value pairs. all options are optional. see below.
  23      where - the $(element) to inject the flash object.
  24  
  25  Properties:
  26      width - int, the width of the flash object. defaults to 0.
  27      height - int, the height of the flash object. defaults to 0.
  28      id - string, the id of the flash object. defaults to 'Swiff-Object-num_of_object_inserted'.
  29      wmode - string, transparent or opaque.
  30      bgcolor - string, hex value for the movie background color.
  31      vars - an object of variables (functions, anything) you want to pass to your flash movie
  32  
  33  Returns:
  34      the object element, to be injected somewhere.
  35      Important: the $ function on the OBJECT element wont extend it, will just target the movie by its id/reference. So its not possible to use the <Element> methods on it.
  36      This is why it has to be injected using $('myFlashContainer').adopt(myObj) instead of $(myObj).injectInside('myFlashContainer');
  37  
  38  Example:
  39      (start code)
  40      var obj = new Swiff('myMovie.swf', {
  41          width: 500,
  42          height: 400,
  43          id: 'myBeautifulMovie',
  44          wmode: 'opaque',
  45          bgcolor: '#ff3300',
  46          vars: {
  47              onLoad: myOnloadFunc,
  48              myVariable: myJsVar,
  49              myVariableString: 'hello'
  50          }
  51      });
  52      $('myElement').adopt(obj);
  53      (end)
