Detailed Description

template<typename T, typename A = std::allocator<T>>
class Dune::Amg::Hierarchy< T, A >

A hierarchy of coantainers (e.g. matrices or vectors)

Because sometimes a redistribution of the parallel data might be advisable one can add redistributed version of the container at each level.
