/**
   *  @brief  Reference to arbitrary subset of an array.
   *
   *  An indirect_array is a reference to the actual elements of an array
   *  specified by an ordered array of indices.  The way to get an
   *  indirect_array is to call operator[](valarray<size_t>) on a valarray.
   *  The returned indirect_array then permits carrying operations out on the
   *  referenced subset of elements in the original valarray.
   *
   *  For example, if an indirect_array is obtained using the array (4,2,0) as
   *  an argument, and then assigned to an array containing (1,2,3), then the
   *  underlying array will have array[0]==3, array[2]==2, and array[4]==1.
   *
   *  @param  Tp  Element type.
