This function sets the values of 
  the parameters controlling the iterative behaviour
  of the Metropolis-Hastings
  simulation algorithm. It uses default values
  that would be appropriate for the fitted point
  process model model.
The expansion parameter expand is set to
  default.expand(model, w).
All other parameters revert to their defaults given in
  rmhcontrol.default.
  
See rmhcontrol for the full list of control parameters.
  To override default parameters, use update.rmhcontrol.
