Functions
void	ByGenLeft (Complex_f a[nc], const unsigned short gen)
	Multiply leaf (or part of one) by generator from left.
void	ByGenRight (Complex_f a[nc], const unsigned short gen)
	Multiply leaf (or part of one) by generator from right.
void	Half_Leaf (Complex_f Leaves[nc], Complex_f *ut[nc], Complex_f a[nc], unsigned int *iu, unsigned int *id, const unsigned int i, const unsigned short mu, const unsigned short nu, const unsigned short leaf)
	Calculates the first half of the leaf for a clover term. We split it so that the force term can reuse the first half of the leaf.
void	Half_Leaves (Complex_f *hLeaves[2], Complex_f *ut[2], unsigned int *iu, unsigned int *id, const unsigned short mu, const unsigned short nu)
	Calculates the products of the first two links in a plaquette.
void	Leaf (Complex_f Leaves[nc], Complex_f *ut[nc], unsigned int *iu, unsigned int *id, unsigned int i, const unsigned short mu, const unsigned short nu, const unsigned short leaf)
	Calculates a leaf for a clover term.
void	Clover (Complex_f *clover[2], Complex_f *ut[2], unsigned int *iu, unsigned int *id)
	Calculates the clovers in all directions at all sites.
void	ByClover (Complex *phi, Complex *r, Complex *clover[2], Complex *sigval, const float akappa, unsigned short *sigin, bool dag)
	Clover analogue of the Dslash operation. This version acts on all flavours similar to Dslash and Dslash_d.
void	HbyClover (Complex *phi, Complex *r, Complex *clover[2], Complex *sigval, const float akappa, unsigned short *sigin, bool dag)
	Clover analogue of the Dslash operation. This version acts on all flavours similar to Dslash and Dslash_d.
void	ByClover_f (Complex_f *phi, Complex_f *r, Complex_f *clover[2], Complex_f *sigval, const float akappa, unsigned short *sigin, bool dag)
	Clover analogue of the Dslash operation. This version acts on all flavours similar to Dslash and Dslash_d.
void	HbyClover_f (Complex_f *phi, Complex_f *r, Complex_f *clover[2], Complex_f *sigval, const float akappa, unsigned short *sigin, bool dag)
	Clover analogue of the Dslash operation. This version acts on all flavours similar to Dslash and Dslash_d.
static void	GetBilinear (Complex_f Z[nc *nc], Bilinear_a Xmn, unsigned int ind)
	Loads the compacted bilinear form into a \(2\times2\) complex valued matrix.
void	CalcXmunu (Bilinear_a Xmunu, Complex_f *X1, Complex_f *X2, const Complex_f *sigval, const unsigned short *sigin, const unsigned short mu, const unsigned short nu)
	Gets \(X_{\mu\nu}\) for the clover force.
static void	GLeft (Complex_f out[4], const Complex_f G[2], const Complex_f X[4])
	Multiplies \( X_{\mu\nu}\) by a gauge field from the left.
static void	GRight (Complex_f out[4], const Complex_f G[2], const Complex_f X[4])
	Multiplies \( X_{\mu\nu}\) by a gauge field from the right.
static void	GSandwich (Complex_f out[4], Complex_f tmp[4], const Complex_f Gl[2], const Complex_f X[4], const Complex_f Gr[2])
	Multiplies \( X_{\mu\nu}\) by a gauge field from the left and the right.
void	Clov_Force (double *dSdpi, Complex_f *ut[2], Complex_f *X1, Complex_f *X2, const Complex_f *sigval, const unsigned short *sigin, unsigned int *iu, unsigned int *id, const float akappa)
	Gets the clover contribution to the force.
int	Init_clover (Complex **sigval, Complex_f **sigval_f, unsigned short **sigin, float c_sw)
	Initialise values needed for the clover terms.
void	Clover_free (Complex_f *clover[nc])
	Free's memory used for clover terms and leaves.
