The density estimator class is an abstract class to estimate the density of a point
in some space given a list of weighted samples on that space. This class is principally
used in Particle BP, where new samples for BP are generated from the estimate of the posterior.
The density estimator is used in PBP to estimate densities during a Metropolis-Hastings sampler
