User-defined operations
=======================

In addition to neuron models, the user can provide functions that are to be called every timestep
during the simulation, using the decorator :func:`network_operation`::

  @network_operation
  def myoperation():
      do_something_every_timestep()

The operation may be called at regular intervals by defining a clock::

  myclock=Clock(dt=1*ms)
  
  @network_operation(myclock)
  def myoperation():
      do_something_every_ms()
