... | Reduce implementation, returns smaller tuple or value1 if both tuples are
equal. Comparison highly depends on the order and amount of fields chosen
as indices. All given fields (at construction time) are checked in the same
order as defined (at construction time). If both tuples are equal in one
index, the next index is compared. Or if no next index is available value1
is returned.

This constructor uses two hard coded choices for the constants needed to build a hash code.

It uses <code>AccessibleObject.setAccessible</code> to gain access to private fields. This means that it will
throw a security exception if run under a security manager, if the permissions are not set up correctly. It is
also not as efficient as testing explicitly.
