void contract_at_t	(	dcomplex &	corr,

		const Field_F &	v1,
		const Field_F &	v2,
		const int	time
	)

Contraction of hadron for 4-spinor fermion.

This class calculates contraction of hadron for 4-spinor fermion. 15 Mar 2012 H.Matsufuru Add momentum of sink. [21 Mar 2015 Y.Namekawa] Add functions contract_at_x(), contract_at_y(), contract_at_z() to measure spatial correlation functions. Add functions contract_at_?() to measure correlation functions directly by corr_global(t)=sum_{xyz}(v2^*)_alpha(t)(gm_sink)_{alpha,beta}(v1)_beta(t). Add functions contract_at_?_cos() to measure Fourier transformed correlation functions in terms of cos by corr=sumcos(px)(v2^*)_alpha(t)(gm_sink)_{alpha,beta}(v1)_beta(t). Add functions global_corr_x(), global_corr_y(), global_corr_z() which should always be used with contract_at_?(). A function global_corr_t() is moved here from corr2pt_4spinor.h .
