Classes
class	hitfit::Fourvec_Constraint_Calculator
	Concrete realization of the Constraint_Calculator class. Evaluate constraints at the point described by x and y (well-measured and poorly-measured variables, respectively). The results should be stored in F. Bx and By should be set to the gradients of F with respect to x and y, respectively. More...
