apply_operator_itrunc_node()

SRDef syten::BTT::apply_operator_itrunc_node	(	State::Ptr	aptr,
		const Operator::Ptr	optr,
		Index	direction,
		bool const	cache,
		Truncation	trunc
	)

Helper for apply_operator_itrunc_rec().

Applies the operator component node optr to the state component node aptr and then does a SVD of the parent node of aptr over the direction-th leg.
