Construct the Jacobian Matrix

Parameters

c1	and c2 are the results constraint sparse matrix
cIndex	is the index of the next constraint equation: when building the constraint matrix, you have to use this index, and then update it
x1	and x2 are the position vectors used for contraint equation computation
cParams	defines the state vectors to use for positions and velocities. Also defines the order of the constraint (POS, VEL, ACC)

This is the method that should be implemented by the component

	)

virtual

Construct the Jacobian Matrix

Parameters

c1	and c2 are the results constraint sparse matrix
cIndex	is the index of the next constraint equation: when building the constraint matrix, you have to use this index, and then update it
x1	and x2 are the position vectors used for contraint equation computation
cParams	defines the state vectors to use for positions and velocities. Also defines the order of the constraint (POS, VEL, ACC)
