Include more built-in Constraints.

zfit.constraint.SimpleConstraint(func, params)

Constraint from a (function returning a) Tensor.

zfit.constraint.GaussianConstraint(params, ...)

Gaussian constraints on a list of parameters to some observed values with uncertainties.

zfit.constraint.nll_gaussian(params, ...)

Return negative log likelihood graph for gaussian constraints on a list of parameters.
