  """
  Compute the Gaussian density at x for a 2D normal distribution with parameters mean, stddev, correlation.
  
  This works simultaneously on a batch of inputs.  The inputs should have dimensions: 
    x.shape = (n, 1, 2)
    mean.shape = stddev.shape = (n, m, 2)
    correlation.shape = (n, m, 1)
  where n*m is the number of different Gaussian density functions that we want to evaluate, on n input points x.  
  So the same input x is plugged into the density for m Gaussian pdfs.  (This is convenient for evaluating a
