Detailed Description

Constructors are templated so that a GncInt128 can be constructed from any arbitrary integer type or pair of integer types.

Note

If the two parameters are of differing sign, it's taken to mean that the lower magnitude is reducing the magnitude of the upper, so the lower magnitude will be subtracted from UINT64_MAX to obtain the lower limb value.
