Helper template to clone the type definition of a std::tuple with the storage types replaced by a user-defined rule.

Suppose all storage types A_i in a std::tuple define a type A_i::B. You can build up a pair consisting of the types defined by A_i::B in the following way:

template <class A>
struct MyEvaluator
{
typedef typename A::B Type;
};
typedef ForEachType<MyEvaluator, ATuple>::Type BTuple;

Here, MyEvaluator is a helper struct that extracts the correct type from the storage types of the tuple defined by the tuple ATuple.
