Model that simulates sampling error incurred by the MLE or ALE methods of
reconstructing likelihoods from sample data. The true likelihood given by an
underlying model is perturbed by a normally distributed random variable
:math:`\epsilon`, and then truncated to the interval :math:`[0, 1]`.
The variance of :math:`\epsilon` can be specified either as a constant,
to simulate ALE (in which samples are collected until a given threshold is
met), or as proportional to the variance of a possibly-hedged binomial
estimator, to simulate MLE.
:param Model underlying_model: The "true" model to be poisoned.
:param float tol: For ALE, specifies the given error tolerance to simulate.
