Detailed Description

template<size_t N, typename F, typename T, size_t M = N>
struct H5Utils::internal::DataFlattener< N, F, T, M >

Data flattener class: this is used by the writer to read in the elements one by one and put them in an internal buffer.

We use a struct rather than a full blown class. Like all things in the internal namespace, you should not mess with this unless you really know what you are doing.
