Class Description

  Manages buffers for branches of a Tree.
  See picture in TTree.

               Default contructor

            Basket normal constructor

          Basket destructor

      Increase the size of the current fBuffer up to newsize

      Drop buffers of this basket if it is not the current basket

*-*              =========================================

       Read a basket buffer. Check if buffers of previous ReadBasket
       should not be dropped. Remember, we keep buffers
       in memory up to fMaxVirtualSize.
