  -  class Tango
  
-  extends Figur
  
Tango: Stores the information of the tango figures.
To initialize a spezial figur:
  Figur figur = new Tango(app, figNum, tempo, audioURL);
Whereat app the applet pointer is, figNum the number of the
tango figur you want, tempo the speed of the sound defined
by the audioURL.
To add a new figur:
 - Add the name of the figur into FigNames_{eng,ger}.
 
 - Add an initialization function (use initLeftTurn as template)
 
 - Add your initialization function into the switch statement of
    the constructor.
 
If you don't have more than 4 figures, you don't have to change anything
in class Dance. If you have more figures, you only have to add more space
for the figur-buttons.
