computeBoundaryForce()

HOSTDEVICE void computeBoundaryForce	(	const dVec &	latticeSite,
		const dVec &	boundarySite,
		const boundaryObject &	bObj,
		dVec &	force
	)

compute the force on lattice site exerted by the boundary site

these boundary force and energy functions use the information at the boundary site to pass additional information. For instance, given homeotropic anchoring the boundary site should have a q tensor which is Q^B = 3 S_0/2*(\nu^s \nu^s - \delta_{ab}/3), where \nu^s is the locally preferred director. For degenerate planar anchoring the boundary site should be, Q^B[0] = \hat{nu}_x Q^B[1] = \hat{nu}_y Q^B[2] = \hat{nu}_z where \nu^s = {Cos[[Phi]] Sin[[theta]], Sin[[Phi]] Sin[[theta]], Cos[[theta]]} is the direction to which the LC should try to be orthogonal
