[boost] more (hyper)complex types

Hallo Developers, Hello John, I'm missing the (hyper)complex types in boost::math: - dual, i²=0 https://en.wikipedia.org/wiki/Dual_number - acomplex (anormal complex), i²=1 https://en.wikipedia.org/wiki/Split-complex_number - sedenion, https://en.wikipedia.org/wiki/Sedenion and the arithmetic functions for this types. Can you provide it? That would be great! thx Gero
