\n A child level getChildLevel() is a xsheet reduced to level.
   The class allows to edit xsheet getXsheet(), change xsheet setXsheet() and
change

   It's possibile change level name setName() and know how many frame are in
level
   getFrameCount().

   The class provides methods to control child level icon, makeIcon(), getIcon()
