docs: Perform one time step of the Temporal Memory algorithm.
  
      This method calls :meth:`activateCells`, then calls 
      :meth:`activateDendrites`. Using :class:`TemporalMemory` via its 
      :meth:`compute` method ensures that you'll always be able to call 
      :meth:`getPredictiveCells` to get predictions for the next time step.
  
      :param activeColumns: (iter) Indices of active columns.
  
      :param learn: (bool) Whether or not learning is enabled.
