orthogonalise_arithmetic_imp() [2/2]

template<typename T , typename Iterator >

auto syten::orthogonalise_arithmetic_imp	(	T &	vec,
		Iterator	first,
		Iterator	last,
		Truncation const &	trunc = Truncation(),
		bool	assume_norm_one = false,
		int	= 0
	)		-> decltype(vec.truncateKeepNorm(trunc), void())

orthogonalise_arithmetic(): Preferred implementation, used if truncateKeepNorm() exists.

Does two loops, since the truncation may induce some error.
