Detailed Description

   template<class _Tp>
       class std::indirect_array< _Tp >" 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.

       Parameters:
           Tp Element type.
