description:
  The classic Metropolis algorithm.
  .
  Wander around parameter space according to a simple spherical Gaussian
  distribution.
  .
  Exports a 'mcmc' function that prints a trace to stdout, a 'chain' function
  for collecting results in-memory, and a 'metropolis' transition operator that
  can be used more generally.
