docstr: Log a histogram for given name on given step.
  
  Args:
      name (str): name of the variable (it will be converted to a valid
          tensorflow summary name).
      value (tuple or list): either list of numbers
          to be summarized as a histogram, or a tuple of bin_edges and
          bincounts that directly define a histogram.
      step (int): non-negative integer used for visualization
