MetropolisSamplerT Class

Metropolis sampling produces samples from distribution P by sampling from a proposal distribution Q and accepting/rejecting based on the density of P. Metropolis sampling requires that the proposal distribution Q is symmetric. All densities are required to be in log space. The Metropolis sampler is a stateful sampler. It keeps track of where it currently is in the domain of the distribution P.
