B2DTuple2D, B2ITuple2D and B2I64Tuple share a lot in common so we can generalise it as a template class. The same goes for the 3D variants - B3DTuple and B3ITuple. This is the initial attempt, but doesn't yet generalise all that is possible. Add some tests for the tuple variants that test the behaviour of overloaded operators and other common methods.
