tuple_view - tuple shape transformation
#include <cfl/tuple/tuple_view.hpp>
template <typename U, typename K> struct tuple_view_c;
Changes the shape of a tuple, i.e. rearranges elements but does not change their
values. An example is transposition of tuples. The orignal tuple U is stored
in the tuple_view_c container and then tuple element access atK uses the
provided table K for lookup.
tuple_view_c is primarily used for implementation details, and not intended
for the end user. Manually specifying the lookup table K can be both error
prone and tedious.
