Detailed Description

template<class T>
struct Zero< T >

The point of this class is to be a number of type T which is known at compile time to be zero.

This is reflected in the operations like addition and subtraction that use it. If you return a Zero object, the compiler should be able to make better optimizations than if you just return zero.

Zero is templated on type T, to represent a zero object of type T. Type T is required to be constructable from an integer zero.
